Claims

[Scope of utility model registration request]

A main body forming an internal cavity, a worm wheel rotatably inserted into the internal cavity and rotatable integrally with the camshaft of the cam brake, and a worm wheel that meshes with the worm wheel to fit into the cavity a worm that is rotatably disposed; a worm shaft that is rotatable integrally with the worm, is supported by the main body, and has one end protruding outside the main body;
an adjusting ring integrally attached to the protruding end of the worm shaft; an annular movable body rotatably fitted to the protruding end of the worm shaft in opposition to the adjusting ring; a one-way clutch that connects an adjustment ring so as to be relatively rotatable in only one direction; a block that is integrally attached to the movable body by friction welding; and a cover that covers the adjustment ring and is fixed to the block. and the block is rotated in response to excessive rocking of the main body.
In the gap adjustment device, the block has a space into which the cover can be fitted, and one of the rotations is transmitted to the adjustment ring via the one-way clutch. , a step part is disposed within the cavity, and a cylindrical part that fits into the cavity on the cover;
A gap adjustment device comprising elastically deformable legs having claws that can be engaged with the stepped portions at the ends of the cylindrical portion.
