Document Type and Number:
Japanese Patent JP2018115734
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the fall of sleeves.SOLUTION: A rotation transmission mechanism 1 includes cam rings 41, 42, 43 to be rotated integrally with an input shaft 2, sleeves 51, 52, 53 provided movable on the outer peripheries of the cam rings 41, 42, 43 in the direction of a rotation axis Xa and rotatable integrally with the cam rings 41, 42, 43, and first-speed gear 21, a second-speed gear 22 and a third-speed gear 23 (transmission gears) rotatably supported on the rotation axis Xa at its positions adjacent to the cam rings 41, 42, 43, where the sleeves 51 is displaced in the direction of the rotation axis Xa for engaging/disengaging the first-speed gear 21, the second-speed gear 22 and the third-speed gear 23 with/from tooth parts 56, 26 provided on mutually opposed portions of the sleeves 51, 52, 53 to select rotation transmission/non-transmission between the input shaft 2 and each of the first-speed gear 21, the second-speed gear 22 and the third-speed gear 23. Between the inner peripheries of the sleeves 51, 52, 53 and the outer peripheries of the cam rings 41, 42, 43, bearings are laid.SELECTED DRAWING: Figure 7
