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 the slider penetrates an opening in the lock member and variably contacts the lock member at a contact location at a surface defining the opening, the slider is provided at the contact location with a sloped portion that is linearly sloped toward the steering shaft along a slide direction of the slider, and the lock member is provided at the surface defining the opening with a sloped portion that is linearly sloped toward the steering shaft along a slide direction of the slider, the sloped portion of the slider and the sloped portion of the lock member 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 from 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.
