Claims

[Scope of utility model registration request]

A pedestal comprising receiving members arranged parallel to each other at a predetermined interval and a connecting member connecting the receiving members at a rear end, and a locking part disposed at a predetermined upper part in front of the pedestal. and an extrusion member that is attached to the inside of the connecting member and is movable in the front-rear direction, and each of the receiving members has a fitting protrusion at the bottom of both ends in the longitudinal force direction, and a protrusion in the longitudinal force direction. A locking part having a locking protrusion at the lower part is provided on the outer side of the central part, and a locking part that is movable in the front and back direction by the operation of an actuator is provided in the locking part, and a locking part that is movable in the front and back direction by the operation of an actuator is attached to one of the receiving members. One side member of the axle box is fitted between the fitting protrusions of the members, and the locking protrusion of the receiving member is inserted into the splash-killing bolt hole formed in the one side member. In the fitted state, the other side member of the axle box is fitted between the fitting protrusions of the other receiving member, and the locking protrusion of the receiving member is formed on the other side member. It is inserted into the spring killing bolt hole, and the locking element of the locking part is located at a position where it can be locked into or released from the axle box guide pin hole of the axle box, and the center of the extruded member is located in the axle box guide pin hole. A roller bearing extraction device for a vehicle axle box, whose specifications are set so that it faces the center of the roller bearing.
