In this design, the lower limb portion 110 and the upper limb portion 150 are combined with a conventional crank arm and a pedal (not shown) to drive the lower limb portion 1 and the upper limb portion 15A. Fig. 2 is a cross-sectional view showing the internal structure of the lower limb portion of Fig. 1. As shown in FIG. 2, the lower limb portion 11A includes a first shaft lu, a second shaft 121, and a third shaft 131. 8 1336302 The first shaft 111 is axially coupled to a pair of leg motion pedals (not shown) and is rotated as a drive shaft ' by the knight's leg pedaling action. The first shaft 111 is provided with housings 112a and 112b and bearings on both sides to obtain support. The output pulley 113 is fitted over the first shaft 5 111 near the inside of the outer casing 112a to connect the load portion 190 with a general belt. At this time, the output pulley 113 has a one-way clutch bearing therein. When the first shaft hi is rotated forward, the output pulley 113 can be restrained and then connected to the load portion 19A. On the other hand, when the first shaft 111 is rotated backward, the output pulley 113 is not > is restrained. The first shaft reverse pulley 116 is mounted around the first shaft 111 in the other casing U2b. The first shaft reverse pulley 116 is provided with a reverse one-way clutch bearing, and when the first shaft 111 is rotated backward, the first shaft reverse pulley 116 is restrained. On the other hand, when the first shaft ηι is rotated forward, the first shaft reverse pulley 116 is not restrained. The first shaft reverse drive pulley 117 is mounted around the first shaft reverse pulley • 116 — around the first axis U1. At this time, the first shaft reverse transmission belt 117 L has an elongation exceeding the first shaft reverse pulley ία to be lightly coupled with the output pulley 113. In other words, the extension U4 extends from the other side of the output pulley ii3 to be integral with the pulley such that the extension = first shaft reverse drive pulley 117 is coupled. The one-way clutch bearing is embedded between the shaft reverse drive pulley 117 and the extension portion 114. When the first shaft 5 is rotated forward toward the drive pulley 117, the output pulley 113 is not restrained, and conversely, when the first shaft is reversed When the drive pulley 117 is turned backward, the output pulley 113 is not restrained by 9 isn., and the first shaft reverse drive pulley is coupled with the external input pulley/disaster to receive the driving force of the upper limb portion 150. One axis ^2 to axis 121 is mounted below the first axis 1U, and the third axis 131 is located below the first axis. The second shaft 121 and the third shaft 131 are supported by a single outer casing 122 1 , and the bearing is embedded between the outer casing 122 and the respective shafts 121 and 131.

The first shaft reverse drive pulley ι6, the second shaft reverse transmission, the pulley 123 and the third shaft pulley 133 are connected by a double belt. The first shaft reverse pulley 116 and the third shaft pulley 133 abut against the inner surface of the double belt, and the second shaft reverse drive pulley 123 abuts against the outer surface of the double belt. The second type is a general belt, and the second shaft reverse drive pulley 123 and the first shaft reverse drive pulley 117 are connected to each other by such a belt. Therefore, when the first shaft 111 is rotated forward, the one-way clutch bearing embedded in the output pulley 113 is restricted, so that the output pulley 113 and the load portion 190 are rotated forward. On the other hand, when the first shaft 111 is rotated backward, the reverse one-way clutch bearing (RCB) embedded in the first shaft reverse pulley 116 is restricted to make the first shaft reverse pulley 116 and the third shaft pulley 133 backwards it = Ϊ Two-axis reverse drive pulley 123 rotates forward. Then, the bearing H pulley 117 is rotated forward by the unidirectional clutch that is embedded in the thin one-way clutch, and the output pulley (1) and the load portion are still rotated forward. f is a cross-sectional view showing the internal structure of the upper limb of Fig. 1.

A second shaft pulley 163 and a second shaft gear 166' are attached around the second shaft 161. The second shaft pulley ία is coupled to the first shaft gear 156 by a first belt pulley 153'. 11 - The second shaft pulley 163 is embedded with a one-way clutch bearing, and only when (6) is rotated forward, the second shaft pulley 163 is restricted by the one-way alignment bearing and then rotated forward. When the first axis 151 is rotated forward by the younger brother, the 'the-axis pulley 153 154 outputs the pulley 153 to the output pulley 153 and the upper limb. Therefore, the external input pulley 180 and the output pulley (1) of the lower limb portion are rotated forward to drive the load portion. I5fi if on the one hand, when the first shaft 151 is rotated backward, the first shaft gear 6. Rotating backwards causes the second shaft gear 166 and the second shaft 161 to rotate forward. Therefore, the second shaft pulley 163 is restrained to the second shaft 161, causing the second pulley 153 to rotate forward. The lower-action is also the same as the first axis to the moon Ij. Although the preferred embodiment of the present invention has described the upper limb portion 150 and the lower limb portion 110 of the two-way pedal exercising foot, only one of the two (i.e., the upper limb portion 150 or the lower limb portion 11A) is provided in the present invention.
