Claims

[Scope of utility model registration request]

A door lock in which a coil spring is fitted onto the outer periphery of a cylinder or thumb turn body having a large diameter portion at the front end, and a collar having a spring seat that receives the rear end of the coil spring is fitted onto the outer periphery of the body against the force of the spring. In the collar mounting structure, a protrusion that protrudes in the radial direction and a passage groove for the protrusion that allows the collar to move in the axial direction are provided relative to each other on the spring seat of the collar and the outer periphery of the body of the cylinder or thumb turn. A collar mounting structure for a door lock, characterized in that a protrusion can be locked in a rotational position by a circumferential locking groove connected to a groove end or by a rear surface of a spring seat.
