BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a striking plate. In particular, the present invention relates to a striking plate for a golf club head. [0003] 2. Description of Related Art [0004] U.S. Pat. No. 6,506,129 (corresponding Taiwan Utility Model Publication No. 557806) discloses a golf club head capable of enlarging a flexible area of a ball-hitting face thereof. As illustrated in FIG. 1 of the drawings, the golf club head comprises a body 10 and a striking plate 20. The body 10 comprises a toe 11, a heel 12, a crown (or blade) 13, a sole 14, a hosel 15, and a coupling section 16. The coupling section 16 is formed along a perimeter of a front side of the body 10. The striking plate 20 includes a striking face 21 and a perimeter wall 22 bent rearward along a perimeter edge of the striking face 21. The striking plate 20 is thus U-shaped in section. An end portion 221 of the perimeter wall 22 of the striking plate 20 is engaged with the coupling section 16 of the body 10 by welding or brazing. After assembly, the striking plate 20 and the body 10 together form a golf club head. When hitting a golf ball, the perimeter wall 22 improves the elastic deformability of the striking face 21 of the striking plate 20, thereby providing improved striking effect. [0005] A design trend for golf club heads is to shift the center of gravity of a golf club head downward to increase the inertia moment and to increase the distance through which a ball hit by the golf club head flies. The lower the center of gravity, the closer the sweet spot of the striking plate 20 to the sole 14 of the body 10. In this case, the elastic deformability of the perimeter wall 22 of the striking plate 20 adjacent to the sole 14 is the main factor. The perimeter wall 22 has uniform elastic deformability. In other words, every portion of the perimeter wall 22 has the same elastic deformability. However, the elastic deformation provided by the sweet spot is limited on the premise that the width of the perimeter wall 22 adjacent to the sole 14 is not increased. Similar situation exists when the center of gravity of the golf club head is shifted upward. [0006] Further, although the elastic deformability of the striking plate 20 is improved by the perimeter wall 22, stress concentration is apt to occur between the end portion 221 of the perimeter wall 22 and the coupling section 16 of the body 10. Cracking is liable to occur in the perimeter wall 22 or welding bead at the location of the stress concentration although the location of the stress concentration varies according to different types of the golf club head. As a result, the striking plate 20 might be disengaged or damaged and the life of the golf club head is shortened. OBJECTS OF THE INVENTION [0007] An object of the present invention is to provide a golf club head with improved vibration resistance. [0008] Another object of the present invention is to provide a golf club head with improved elastic deformability. SUMMARY OF THE INVENTION [0009] In accordance with an aspect of the present invention, a golf club head comprises a body and a striking plate mounted to the body. The body comprises a coupling section at a front side thereof. The striking plate comprises a striking portion for striking a golf ball and a perimeter wall extending rearward along a perimeter edge of the striking portion. The perimeter wall comprises an end portion for coupling with the coupling section of the body. At least one reinforcing protrusion is formed on an inner face of the perimeter wall for improving vibration resistance of the body and the striking plate. Preferably, the perimeter wall has a width that varies along a perimeter length thereof. [0010] In accordance with another aspect of the invention, a golf club head comprises a body and a striking plate mounted to the body. The body comprises a coupling section at a front side thereof. The striking plate comprises a striking portion for striking a golf ball and a perimeter wall extending rearward along a perimeter edge of the striking portion. The perimeter wall comprises an end portion for coupling with the coupling section of the body. The perimeter wall includes a width that varies along a perimeter length thereof for improving elastic deformability of a sweet spot of the striking portion. [0011] Preferably, the at least one reinforcing protrusion is located corresponding to at least one stress-concentrating area on the inner face of the perimeter wall. [0012] Preferably, the at least one reinforcing protrusion is located on the inner face of a bottom portion or a top portion of the perimeter wall and adjacent to a toe or a heel of the body. Alternatively, the at least one reinforcing protrusion is located on the inner face of a toe-side-portion of the perimeter wall. [0013] Preferably, the width of the perimeter wall varies in a continuous or discontinuous manner. [0014] Preferably, variation of the width of the perimeter wall is positively related to a location of the center of gravity of the golf club head and a location of a sweet spot of the striking plate. [0015] Preferably, the width of a bottom portion of the perimeter wall is greater than that of a top portion of the perimeter wall. In an alternative example, the width of the top portion of the perimeter wall is greater than that of the bottom portion of the perimeter wall. In another alternative example, the width of a toe portion of the perimeter wall is greater than that of a heel portion of the perimeter wall. In a further alternative example, the width of the heel portion of the perimeter wall is greater than that of the toe portion of the perimeter wall. [0016] Preferably, the front side of the body further comprises a sidewall portion substantially orthogonal to the coupling section. Preferably, the perimeter wall of the striking plate comprises a side opening adjacent to a heel of the body for coupling with the sidewall portion of the body. [0017] Other objects, advantages and novel features of this invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
