徴とする車両用デフロツク装置。 A clutch portion 21 is provided on the end surface of the boss portion 20 of the differential case 12 in the differential mechanism 10, and a clutch cylinder shaft 22 provided with a clutch portion 24 that can be freely engaged and disengaged from the clutch portion 21 is slid onto the differential output shaft 19 only in the axial direction. Both clutch parts 21 and 24 are movably fitted into the mantle.
are opposed to each other with an interval in the axial direction, and a spring 26 that biases them in a direction away from each other is attached to the differential output shaft 19.
In a vehicle deflock device having an operating arm 29 which is fitted over the clutch cylinder shaft 22 and pushes the clutch cylinder shaft 22 in the diffraction direction against the spring 26, the clutch cylinder shaft 22 is pushed back by the biasing force of the spring 26.
1. A vehicle differential lock device, characterized in that a stopper portion 27 is provided on a differential output shaft 19, and a stopper portion 27 is provided on the differential output shaft 19 so as to be in contact with the stopper portion 27 so as to be able to freely approach and separate from the stopper portion 27, thereby regulating the amount of return.
