Claims

[Scope of Claim for Utility Model Registration] An Atsupa column rotatably supports an Atsupa steering shaft with a steering wheel fixed to its upper end, and the Atsupa column rotatably supports a lower steering shaft fixed to the vehicle body and connected in the direction of the Atsupa steering shaft. It is tiltable around a tilt pin with respect to a column bracket that is integrally connected to the supporting lower column, and one of the upper column or column bracket has a fixed gear member, and the other has a movable gear member that can mesh with the fixed gear member. When the gear member is fixed and both gear members are in mesh, the lock member prevents the movable gear member from rotating.If necessary, by operating the operating member and activating the lock member, both gear members can be rotated. In a tilt steering device capable of disengaging gear members, the lock member has a U-shape, and an engagement member that can engage with the movable gear member is fixed to an intermediate portion thereof; The operating member is pivoted at both ends by a tilt pin, and a mounting member for the operating member is provided in the vicinity of the lock member so as to be rotatable about an axis parallel to the tilt pin. A hole is provided on the other side, and a shaft member extending loosely through the hole is provided on the other side, and when the mounting member is rotated, the locking member is rotated.Furthermore, the mounting member has an abutting portion, Each of the locking members is formed with abutted parts that can be brought into contact with the corresponding contact parts, and the corresponding contact parts and the abutted parts face each other at a small distance when the operating member is in the tightening position. When the operating member is operated to the release position, it is in a position where it cannot make contact, and furthermore, when it is in the operating position, a force is applied to the locking member to release the movable gear member from the fixed gear member due to a so-called secondary collision. The tilt steering device is characterized in that this is prevented by the abutting member abutting the abutted member.
