Handlebar locking device

摘要

A protector block (28) is movable in a direction in which a key can be inserted, and first engaging portions (28b, 26a) which engage each other when the protector block (28) is pushed in are formed between the protector block (28) and an outer lock cylinder (26). A crankshaft (32) is movable in the direction in which the key can be inserted, and second engaging portions (26b, 32g) which engage each other when the crankshaft (32) is pushed in are formed between the crankshaft (32) and the outer lock cylinder (26). When an object (D) in place of a key is inserted into a key insertion hole (32c) and attempts are made to forcibly turn the object (D) while pushing the object (D), the first engaging portions (26a, 28b) between the protector block (28) and the outer lock cylinder (26) engage each other, preventing the crankshaft (32) from being turned. When attempts are made to turn an inserted object (D) while pulling the object (D), the second engaging portions (26b, 32g) between the crankshaft (32) and the outer lock cylinder (26) engage each other, preventing the crankshaft (32) from being turned. In combination with tumblers (31) preventing the crankshaft (32) from being turned, the above structure makes it highly difficult to unlock the handle lock device.
