Abstract

A lock mechanism of a tubular body includes a housing to which a tubular body is mounted, a lock member locking and unlocking the housing and the tubular body, and a ring member rotatably attached on an outer periphery of the housing and moving the lock member between a lock position and an unlock position. When a locking portion of the lock member is locked to a locked portion of the housing, the lock member is retained in the unlock position. When the tubular body is inserted in the housing to unlock the locking portion and release an urging force accumulated in the lock member, the lock member moves to the lock position together with the ring member to lock the tubular body. When the ring member is slid in an axis direction of the tubular body after being locked, the tubular body can be locked with one touch.
