Abstract: A nozzle device 1 includes a main body 10 that is formed of a main-body first member 11 and a main-body second member 22 and that has an internal accommodation space 21 in which members are accommodated, a movable nozzle portion 30 that is accommodated in the accommodation space 21, and a coil spring 2 that is disposed between the movable nozzle portion 30 and the main body 10. When air is supplied to a main-body flow-path portion 23 from below, the flow path of the air is changed by the Coanda effect in an air guiding portion 27 such that the air flows along the air guiding portion 27, and the air flows into a gap between an air receiving portion 36 and the air guiding portion 27 and is guided to the air receiving portion 36. The air is pressurized in the air receiving portion 36 and pushes up the movable nozzle portion 30.

Abstract: A locking member is mounted to the housing to be able to move in the outer diameter direction by a tapered portion of the tubular body, when the tubular body is inserted. The housing is equipped with slits formed to pass a curved portion bent in the inner diameter direction disposed at a leading-end side of the locking member and to lock with the engagement portion of the tubular body mounted on the housing. A gap is disposed between the curved portion, and the end portion of the slit positioned at a side in an opposite direction to the leading-end side of the locking member, so that there is no contact while at least the locking member is moving.

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.
