ABSTRACT:
A door lock handle assembly comprises a stationary member having a sleeve portion having a shaft bore with the surface thereof provided with a retainer projection, and a handle having a shaft portion having a rear end insertion groove. The shaft portion of the handle is inserted in the shaft bore of the stationary member with the retainer projection and the insertion groove engaged with each other. After completion of the insertion, the retainer projection is accommodated in a front end circumferential escape groove formed as part of the insertion groove.
The shaft portion of the handle is not detached from the sleeve portion of the stationary member when a rotational angle regulation member or a locking member is removed. The Stationary member can be secured to a door, so that by rotation of the handle a lock member can be engaged in a locking groove provided in an adjacent stationary structure.
