PROBLEM TO BE SOLVED: To provide a transmission mechanism capable of ensuring transmission performance stably.SOLUTION: A transmission mechanism includes: a relative rotation driving mechanism that is provided so as to straddle over one composite sprocket and another composite sprocket, and axially moves a plate-like fork for gear change provided parallely to a stationary disc and a movable disc, thereby to relatively rotatably drive the movable disc to the stationary disc and radially move a first intersection place; and a guide mechanism 60 that is connected to the fork 35 for change gear, arranged along an axial direction, and guides axial movement of the fork 35 for change gear.SELECTED DRAWING: Figure 9 |
