  • Publication number: 20110132048
    Abstract: A steering lock device includes a lock member that is slidable between a lock position and an unlock position, and a slider that is disposed slidably in a direction perpendicular to a moving direction of the lock member. A sloped portion that is linearly sloped toward the steering shaft along a slide direction of the slider is provided on at least one of the lock member and the slider. The lock member is shifted between the lock position and the unlock position by the sloped portion in response to sliding of the slider. According to the steering lock device, downsizing can be brought due to its short height along a stroke direction of the lock member and cost reduction by commoditization of its main components can be achieved.
