Claims

[Scope of utility model registration request]

A main shaft consisting of a lower shaft and an upper shaft tiltably connected to the lower shaft, a lower tube rotatably supporting the lower shaft and supported on a part of the vehicle body, and the upper shaft assembled to the upper shaft so as to be tiltable by a predetermined amount. a steering column consisting of an Atsupa tube that rotatably supports the steering column; a ratchet fixedly provided on either one of the two tubes in the steering column; A release lever that engages with the ball during rotation to release its engagement with the ratchet; and a release lever that elastically abuts the back of the ball to lock the ball in the meshed state. In a tilt steering device for a vehicle, the tilt mechanism includes a lock cam that rotates integrally with the release lever when the release lever rotates, separates the ball from the ball, and releases the lock. A tilt steering device for a vehicle, characterized in that a contact portion of the pole is located closer to the center of swing of the pole than a line connecting the center of tilt of the steering column and the center of rotation of the lock cam.
