Abstract: A quick connector includes a tubular socket, a wire retainer attached to an outer circumferential surface of the socket, and a guide member provided inside of the socket. The wire retainer has a lock portion which engages with a flange of a first tubular body when the guide member is at a second position. An outer circumferential surface of the guide member is formed with a holding recess in which the lock portion is fitted when the guide member is at a first position, and a wall of a pair of walls forming the holding recess is formed with a tapered guide surface that extends radially outward. The tapered guide surface guides the wire retainer so that the wire retainer goes over the flange when the first tubular body is inserted.

Abstract: There is provided a valve device for a fuel tank. A housing is provided with a valve chamber and a vent chamber defined via a partition wall. The partition wall is provided with an opening. A float valve is received in the valve chamber to be movable up and down. The float valve includes a lower member and an upper member. The upper member includes a top portion, an outside wall extending from the top portion, and an elastic engaging piece configured to engage with an engaged portion of the lower member. The elastic engaging piece extends from a location on the back surface of the top portion, which is located inward from the outside wall, and is configured to elastically return after being bent in an outward radial direction of the upper member and thus to engage with the engaged portion of the lower member.

Abstract: An electric locking device for an operable/closable member attached to an opening portion, includes a biasing member which biases a pair of rods in a direction in which the rods are brought into engagement with a pair of locking portions, an actuator for sliding the rods to disengage from the locking portions, the actuator having a case having an opening portion, a motor disposed within the case, a worm rotated by the motor and a worm wheel supported rotatably on the case and interlocked with the worm for rotation. The worm wheel has a rotating portion projecting outwards of the case from the opening portion, and proximal end portions of the rods are assembled individually to the rotating portion so as to move in an associated fashion, causing the rods to slide in a synchronized fashion in opposite directions to each other.

Abstract: Provided is a pipe fitting, which is capable of preventing unintended release of a connection between pipes due to an external manipulation and is capable of releasing the connection between the pipes when necessary. This pipe fitting has a housing, a first retainer, and a second retainer. The first retainer has first elastic pieces as well as being slidably disposed inside the housing and being configured so that when the first retainer is located on the connecting section side of the housing, the first elastic pieces are expandable and when the first retainer is located on the inserting section side of the housing, expansion of the first elastic pieces is restricted. An operating pipe section, which can be held at the connecting section end only through an opening in the connecting section of the housing is provided on the second retainer.

Abstract: A check valve includes a valve case, a positive pressure valve, a spring, and a negative pressure valve. The positive pressure valve is slidably disposed in a valve chamber of the valve case. The spring urges the positive pressure valve to abut on a positive pressure valve seat of the valve case. The negative pressure valve is on the positive pressure valve to abut on a negative pressure valve seat of the positive pressure valve. The negative pressure valve closes a communicating passage in the positive pressure valve in a normal state, and opens it when a pressure in the fuel tank falls to a predetermined value or less.

Abstract: There is provided a handle device. The handle device includes a base member, a handle member, and a swing member. The handle member has a grasp portion. The swing member includes a handle-side abutting portion, a base-side abutting portion, and a rotational pivot portion. As the handle-side abutting portion comes away from a bottom portion of the base member, the base-side abutting portion comes close to the bottom portion of the base member.

Abstract: A damper device includes a cylinder, a piston, a seal ring member, and a transmitting portion. The piston includes an annular outer circumferential portion, a first stopper portion, a second stopper portion, and a projecting portion. The projecting portion has an inclined surface which is inclined radially outwards form a side of the second stopper portion towards a side of the first stopper portion. The seal ring member is configured to allow a first chamber to communicate with a second chamber when a portion of the seal ring member which is not restricted by the first stopper portion is deformed in a direction away from the second stopper portion due to friction caused between the seal ring member and the cylinder or a fluid pressure from the second chamber to ride on the inclined surface.
