When the invention shows the bicycle counterclockwise The driven mode convex (4) is shifted to the right end of the positioning tooth 311 at the right end of the positioning tooth 311 after the positioning back 311 is elastically beaten. The position of the first moving element (4) is limited by the moving plate 4 _健=方, however, the driven component core is restricted by the swaying plate 41 to be able to ' and the dancing force of a few pieces of 6 to cause the pawl body 51 to pick up, thereby causing it to abut against the outer cogging 14' Therefore, when the sprocket 12 of the outer casing is driven counterclockwise by the key strip, the seat 2 that is coupled to the rear axle rotates counterclockwise; however, when the key η of the outer casing i is forked to the keybar for clockwise driving, Since the first driving element 5A does not abut the tooth groove 14, it is idling. s The younger brother and the tenth-β picture-age bicycle are operated in a clockwise driving mode. When the first clutch 3 and the second clutch 4 are rotated, the mountain yoke ρ 27 is displaced to the positioning tooth after the plurality of positioning teeth 311 are pulsating, and the first driving element 5 is restricted by the swaying plate 41 to be inserted. Below the swaying plate 41, but the first booklet is not restricted by the swaying plate 41, so that the elastic force of the member 6 can cause the pawl body 51 to rise, thereby making it The abutting end abuts 14 'thus' when the sprocket 12 of the outer casing 1 is clockwise driven by the chain to be readable and coupled to the rear seat 2 of the fixed seat 2 to rotate clockwise; but the outer casing: 2 to the key bar counterclockwise drive Therefore, because the second driving element 5 Α does not have the abutment of the tooth groove 14 , the idling is generated. The present invention is merely a preferred embodiment for explaining the present invention, and is not intended to impose any form on the present invention. Therefore, any modification or modification of the present invention in the spirit of (4) should be included in the scope of the invention. 201236919 [Simplified illustration] The stereoscopic exploded view of the relationship实实·体图弟- The picture shows the drive of the invention The schematic diagram of the embodiment of the outer casing structure of the main component is shown in the front view of the present invention.
