In a pivot portion of an external bicycle transmission, the rewriting frame 6 of a transmission chain is pivotally supported, and the rewriting frame is elastically biased by a coil spring 13 in a direction to remove slack in the transmission chain. Pivot shaft 3 with frame inserted into main body 9
At the same time, a shaft hole 18 is provided on the outside of the bushing 11 which is interposed between the main body and the rewriting frame and one end of the coil spring is hooked thereto, and at least a screw hole 19 is provided on the outside of the rewriting frame that is in contact with the bushing 11. A plurality of holes are provided on one side of the same circumference, and by selecting these holes and screwing the push and rewrite frame onto the detent shaft 20, the rewrite frame, pivot shaft, and bushing are removably fixed. A pivot part structure of an external bicycle transmission, characterized in that:
