Document Type and Number:
Japanese Patent JP7051235
Kind Code:
B2
Abstract:
To improve detection accuracy without requiring high dimensional accuracy.SOLUTION: A rotation transmission mechanism 1 switches engagement and separation of gear tooth portions 26 and sleeve tooth portions 56 disposed on mutual opposed surfaces 25, 55 of shift gears 21, 22, 23 and sleeves 51, 52, 53. The rotation transmission mechanism 1 includes a gear rotation detection mechanism having magnets 29 disposed on inner peripheral surfaces opposed to an outer periphery of an input shaft 2, of the shift gears 21, 22, 23, and magnetic elements 93 disposed on positions in a rotation axis Xa direction same as the magnets 29 of the input shaft 2, and a control device 100 for controlling a driving mechanism 15 on the basis of a result of the detection by the rotation detection mechanism. The rotation detection mechanism detects the magnets 29 when the magnets 29 pass through a circumferential position around the rotation axis Xa of the magnetic elements 93 by relative rotation of the shift gears 21, 22, 23 and the input shaft 2.SELECTED DRAWING: Figure 4
