CYLINDER LOCK

WIPO Patent Application WO/2013/161564

A1

A cylinder lock in which a half tumbler spring-urged toward engaging an engaging part in a locking depression of a cylinder body is inserted in a tumbler insertion hole of a rotor so that the engaging part is separated from the locking depression in response to insertion of a proper mechanical key in a key insertion hole, wherein an inside surface (54) of the tumbler insertion hole (21) is formed so as to have: a guide part (55) extending in the movement direction of the half tumbler (32) and opposing the half tumbler (32) in proximity thereto; and a passage formation part (57) in which the clearance with the half tumbler (32) is larger than that of the guide part (55) therewith, so that an escape passage (59) open at both ends on an outer surface of a rotor (13) is formed in the intervening space with the half tumbler (32), so as to extend in the movement direction of the half tumbler (32), an edge of a key insertion hole (14) facing the escape passage (59). Foreign matter that penetrates into the tumbler insertion hole from the key insertion hole is thereby allowed to escape from the locking depression of the cylinder body, and smooth operation of the half tumbler is ensured.
