Abstract: A connector includes a male member mounted on a connector housing, and a lock member which can engage and disengage between the connector housing and the male member. The connector housing includes a lock-member guide wall guiding the lock member; an engagement projection engaging with one portion of the lock member, and restricting the lock member from descending; a sliding surface where a tip portion slides accompanied by a movement of the lock member; and a through-hole through which one portion of the lock member held by the lock-member guide wall passes, and which is formed to engage with an engagement portion formed on an outer periphery of the male member mounted on the connector housing. In the lock member, the movement is restricted by the engagement projection, and after an engagement with the engagement projection is released, the lock member descends to prevent an unprepared release and ensure safety.

Abstract: A connector includes a cylindrical connector housing having through-holes extending in a circumferential direction formed on right and left, a cylindrical male member to be entered into the connector housing and having a circumferential groove conforming with the through-holes in a state wherein the male member enters into the connector housing; and an elastic lock member including an intermediate portion, and right-and-left leg portions projecting to right and left from the intermediate portion to be received into the through-holes. Sliding inclined surfaces to be engaged with loose ends of the leg portions of the lock member are provided on an outer periphery of the connector housing. The lock member takes an engagement position where the leg portions enter into the circumferential grooves from the through-holes; and a release position where the leg portions escape toward the through-holes from the circumferential groove.

Abstract: A tubular-member lock mechanism includes a cylindrical housing to which a tubular member having an engagement portion at one end is mounted, and a lock member for engaging or releasing the housing and the tubular member. The housing includes a lock-member guide wall turnably guiding the lock member, at least two sliding surfaces with different inclinations wherein a tip portion of the lock member slides by turning the lock member, and a slit through which one portion of the lock member passes to engage the engagement portion of the tubular member mounted to the housing. The lock member, at a standby/lock position, engages the engagement portion formed on an outer periphery of the tubular member, and the lock member, at a release position where a rotational load is applied, spreads by the sliding surfaces having the different inclinations releases the engagement portion of the tubular member.

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 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 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.
