Title:
パーキングロック装置
Document Type and Number:
Japanese Patent JP7059907
Kind Code:
B2
Abstract:
A parking lock device includes a parking gear, a parking pawl, a parking cam, a solenoid actuator, and a power conversion mechanism. The power conversion mechanism is configured to convert reciprocal motion of the plunger to rotary motion of the parking cam in one direction. When the parking cam rotates, a position of a cam surface of the parking cam that abuts the parking pawl is changed, so as to alternately switch between a locked position where rotation of the parking gear is stopped and an unlocked position where meshing between the parking gear and the parking pawl is canceled. A stroke amount of the plunger is reduced in a range where the parking cam can rotate. In this way, the parking lock device can be downsized. Therefore, mountability of the parking lock device on a vehicle is improved.
