BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an exercising apparatus, more particularly to a rowing exercising apparatus. [0003] 2. Description of the Related Art [0004] Referring to FIGS. 1 and 2, a conventional rowing exercising apparatus 1 is shown to comprise a supporting frame 11, a wheel assembly 12, and a restoring unit 13. [0005] The supporting frame 11 includes an elongated bar 111 having front and rear ends, front and rear supporting legs 112, 113 disposed respectively on the front and rear ends of the supporting frame 11, a seat member 114 mounted slidably on the elongated bar 111 and located between the front and rear supporting legs 112, 113, two foot plates 115 mounted respectively on left and right sides of the front end of the elongated bar 111, and a handle bar 116 mounted movably on the front end of the elongated bar 111. [0006] The wheel assembly 12 includes a resistance wheel 121 mounted on the front supporting leg 112, a transmission wheel 122 mounted on the front supporting leg 112 and spaced apart from the resistance wheel 121, a guide roller 123 mounted on the front supporting leg 112 and disposed proximate to the handle bar 116, a transmission belt 124 interconnecting the resistance wheel 121 and the transmission wheel 122, and a pull cord 125 wound around the transmission wheel 122 and having one end extending over the guide roller 123 and connected to the handle bar 116. [0007] The restoring unit 13 includes a hollow body 131 mounted on one side of the transmission wheel 122, and a coil spring 132 disposed within the body 131. The coil spring 132 has a central end connected to a bearing of the transmission wheel 122, and a terminal end connected to the body 131. [0008] The resistance wheel 121 is a magnetically controlled wheel, and creates a resistance during rotation through magnetic force attraction. [0009] When the handle bar 116 is pulled, the pull cord 125 is unwound from the transmission wheel 122, thereby causing the transmission wheel 122 and the resistance wheel 121 to rotate synchronously. The bearing of the transmission wheel 122, in turn, causes the coil spring 132 to wind tightly so as to store a force. When the handle bar 116 is released, the stored force of the coil spring 132 permits restoration of the transmission wheel 122 to its original position. The pull cord 125 is wound back on the transmission wheel 122 at this time. By repeating the abovementioned steps, a rowing exercise is effected. [0010] However, since the coil spring 132 of the restoring unit 13 is made of steel, which is hard and which is less ductile, when the handle bar 116 is suddenly pulled, the coil spring 132 is likely to break easily. Moreover, when the handlebar 116 is released, because of the strong returning force of the coil spring 132, the handle bar 116 is restored swiftly to its original position so that the handle bar 116 bumps into the supporting frame 11, which can damage the latter. SUMMARY OF THE INVENTION [0011] Therefore, the object of the present invention is to provide a rowing exercising apparatus that is capable of overcoming the aforementioned drawbacks of the prior art. [0012] According to this invention, a rowing exercising apparatus comprises a frame, a seat member mounted slidably on the frame, a wheel assembly including a resistance flywheel and a transmission wheel cooperatively mounted on the frame, a pull cord connected to the transmission wheel and having a manual operation end, and a restoring unit including an elastic rope having a fixed end mounted to the frame and a moving end connected to the transmission wheel.
