ABSTRACT:
A protector block is constructed so as to be urged in a key extracting direction and movable in a key inserting direction and is provided with radially outwardly projecting engaging portions which come into engagement with an outer lock cylinder when the protector block is pushed in. The overall length in the key inserting direction of the protector block can be shortened and hence it is possible to construct a handle locking device in a compact shape. Further, in the case where the protector block is fabricated by sintering, the green compact density in powder molding can be made more uniform because it is possible to shorten the length in the key inserting direction.
