PARKING LOCK MECHANISM FOR VEHICLE
Document Type and Number:
Japanese Patent JP2022165766
Kind Code:
A
Abstract:
To suppress increase of a load in moving a lock member caused by axial displacement of a first roller and a second roller.SOLUTION: A first roller 32 and a second roller 34 are disposed on a lock member 14 in a state of having a prescribed play in a radial direction, and any of a first support pin 36, a second support pin 38 and through holes 32h, 34h has a symmetrical shape to smoothly increase a radial dimension symmetrically through an axial center position of the first roller 32 and the second roller 34 at a target arrangement position. By engagement of the first support pin 36, the second support pin 38 and through holes 32h, 34h, the axial positions of the first roller 32 and the second roller 34 are respectively automatically adjusted to the target arrangement positions, and the first roller 32 and the second roller 34 are prevented from being axially displaced and slide-contact with side wall portions 30a, 30b of a roller support body 30, so that a load in moving the lock member 14 is reduced.SELECTED DRAWING: Figure 3
