Abstract
A steering lock device includes a pin protruded from a side surface of an arm of a slider, a guide groove disposed on a housing to accommodate the slider slidably, and a cover wall the pin when the slider positions at its lock end within the guide groove. According to the steering lock device, it can be made difficult to unlock a steering shaft through an improper act, and thereby superior antitheft performance can be brought.
Claims6
A steering lock device comprising:
- a lock member disposed in a housing that is slidable between a lock position at which the lock member engages with a steering shaft to prohibit a rotation of the steering shaft and an unlock position at which the lock member doesn't engage with the steering shaft to allow the rotation of the steering shaft, and urged toward the steering shaft by an urging member;
- and
- a slider disposed in the housing that is slidable between a lock end and an unlock end along a direction perpendicular to a moving direction of the lock member,
- wherein
- a sloped portion that is linearly sloped toward the steering shaft along a slide direction of the slider is provided on one of the lock member and the slider, and a sloped hole is provided on another of the lock member and the slider,
- the sloped portion and the sloped hole are coordinated with each other in response to sliding of the slider to shift the lock member between the lock position and the unlock position, and
- the slider includes an arm and a pin protruded form a side surface of the arm, and the housing includes a guide groove that accommodates the slider slidably and a cover wall that covers the pin when the slider positions at the lock end.
