Abstract
In a cylinder lock (1) one or more (2a, 3a) for locking pins (5) are formed in the cylinder housing (2) and the cylindrical body (3), and the bores in the cylinder housing have a slope relative to a normal to the axis of the cylinder housing. When the cylindrical body is rotated through 180.degree. by a correctly inserted key, a crescent-shaped part of each pin engages the wall of the cylinder housing so that the pins are held in the cylindrical body (2) without falling out through the mouths (2a') of said bores, although said mouths are not plugged. The problem of producing a simple and inexpensive method of manufacture for a cylindrical lock having a smaller number of elements than known locks is thus satisfactorily solved. The slope angle is suitably from 2.degree. to 3.degree..
