Steering lock mechanism of automotive steering device

摘要

A steering lock mechanism (100,200) for a steering device (1) comprises a first structure (3) adapted to be mounted on the steering wheel column (4) and having a key lock rod (7) that is projectable into a lock notch (5a) formed in the steering wheel shaft (2) to lock the steering wheel shaft; a second structure adapted (12) to be provided by the steering wheel column (4); and a coupling/positioning structure that couples the first and second structures together in a manner to achieve a positioning of the first structure relative to the second structure. The coupling/positioning structure includes a projection (10) provided by either one of the first and second structures, the projection having mutually opposed edges (100-1,100-2) which are sloped with respect to a given axis along which the key lock rod (7) moves; and a recess (12) provided by the other of the first and second structures, the recess having mutually opposed edges (120-1,120-2) against which the mutually opposed sloped edges of the projection (10) slidably abut when the projection is pressed into the recess.
