Abstract
Official abstract text for this publication.
An actuator (A) of a steering lock device includes a tubular member ( 17 ) that is fitted around an outer periphery of a lock pin ( 14 ) and is rotated by an electric motor ( 19 ), a helical cam groove ( 14 e ) is provided, among an inner peripheral face of the tubular member ( 17 ) and an outer peripheral face of the lock pin ( 14 ), in the outer peripheral face of the lock pin ( 14 ), a ball ( 21 ) is disposed between the cam groove ( 14 e ) and a ball retaining groove ( 17 a, 17 a ) of the tubular member ( 17 ), and a guide pin ( 23 ) implanted in the lock pin ( 14 ) opposes a cam face ( 17 d ) formed on the inner peripheral face of the tubular member ( 17 ). Even when a bottom part of the ball retaining groove ( 17 a, 17 a ) is worn and the lock pin ( 14 ) cannot be pulled out from a recess ( 12 a ) by the cam groove ( 14 e ), the lock pin ( 14 ) can be pulled out completely from the recess ( 12 a ) by the cam face ( 17 d ) and the guide pin ( 23 ) and, moreover, since the cam groove ( 14 e ) and the cam face ( 17 d ) are provided so as to be divided between the tubular member ( 17 ) and the lock pin ( 14 ), it is possible to achieve a reduction in the size of the actuator (A).
First claim
Opening claim text (preview).
The invention claimed is: 1. A steering lock device that non-rotatably locks a steering shaft by engaging an extremity of a lock pin with a recess formed in an outer periphery of the steering shaft, the lock pin being moved back and forth by an actuator, the actuator comprising an electric motor, a tubular member that encompasses an outer periphery of the lock pin and is rotated by the electric motor, and cam means that is provided on one of an inner peripheral face of the tubular…
