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 that non-rotatably supports the lower shaft and supported on a part of the vehicle body, and the upper shaft attached to the lower tube 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 releasably engaged pawl, a release lever that engages with the ball during rotation to release its engagement with the ratchet, and a resiliently abutted contact with the back of the pawl to lock the pawl in the engaged state. and a tilt mechanism comprising a lock cam that moves integrally with the release lever to separate it from the pole and release the lock when the release lever is rotated, wherein the lock cam of the tilt mechanism is A tilt steering device for a vehicle, characterized in that it is assembled so as to be able to rotate integrally with the release lever at a rotation center thereof.
