PURPOSE: To prevent axial deflection of a main shaft and a follower shaft and smooth clutch action by installing a fixed pawl body and a movable pawl body at axial ends of both shafts, and inserting a protrusion protruded at the center of the axial end of one shaft into the center hole at the axial end of the other shaft.
CONSTITUTION: Both ends of a main shaft 1 is formed to have a square cross section, a fixed pawl body 8 is installed unrotatably by a stop ring 9, and a protrusion 13 is protruded out. In the meanwhile, the protrusion 13 is inserted into a hole 12a formed on the inner side of follower shaft 12 supported by a sleeve 10a, a movable pawl body 14 is spline connected at an inner end part of the follower shaft 12, and a pawl 14a is engaged with a pawl 8a of the fixed pawl body 8 by a spring 15. A pin 16a of a shifter 16 is engaged with an outer circumferential groove of the movable pawl body 14. The main and the follower shafts 1, 12 are thus assembled in a straight line without causing axial deflection, thereby the movable pawl body 14 can be moved smoothly.
