When the elastic members of the two elastic members 71 are respectively attached to the left-handed sticks of the receiving slots, the elastic members 71 of the elastic members 71 are respectively biased against the driving pawls 51. 'The value of the claw portion 512 of the right-hand drive pawl 51 is comminuted with the right-hand drive surface 412 of the ratchet tooth 4U of the spine 1, so that when the chain 7 M382912 wheel 42 is subjected to a clockwise driving force, The right-hand drive pawl 51 can be driven by the ratchet 々η, and the effect of driving the casing 3 in the clockwise direction can be generated. Conversely, when the sprocket 42 is driven in the counterclockwise direction, The right-hand drive pawl 51 will disengage from the ratchet 4, and can only produce idling. When the consumer wants to drive the ratchet hub, the left-hand pawl group 6 is unsuitable as a spare part. As shown in FIGS. 6 and 7, when the consumer wants to drive the ratchet hub, that is, to mount the sprocket 42 of the driving member 40 to the left side, the left-hand pawl of the left-hand pawl group 60 is selected. And a plurality of elastic members 71 of the elastic member group 70 are respectively mounted on the right-hand pivoting portion 342 of the accommodating groove 34, and The elastic abutting portions 713 of the elastic members 71 respectively abut against the left-hand drive pawl 61 to cause the claw portion 612 of the left-hand drive pawl 61 to lie with the left-drive driving surface 413 of the ratchet teeth 411 of the ratchet ring 41. Σσ, such that when the sprocket 42 is subjected to a counterclockwise driving force, the left-hand pawl 61 can be driven by the ratchet teeth 411, and the effect of driving the setting body 30 counterclockwise is generated. Conversely, when the sprocket 42 is subjected to a clockwise driving force, the left-hand drive pawl 61 will be disengaged from the ratchet teeth 411 to release the occlusion, and only the idling can be generated. When the S consumer wants to drive the ratchet hub to the left, the right-hand pawl group 5 is unsuitable as a spare parts. According to the above-mentioned composition, the ratchet hub which can be interchanged with the left and right sides can be used for the purpose of improving the usability and the cost of the purchase. M382912 However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple material effect change and modification according to the novel application and the new description content. , are still within the scope of this new patent.
