Abstract: There is provided a valve device including: a housing; and a float valve. The float valve includes a main float, a sub-float held at an upper portion of the main float to be able to ascend and descend by a predetermined distance with respect to the main float, and a sub-float biasing spring disposed between the main float and the sub-float and configured to bias the sub-float upward with respect to the main float. The sub-float includes a spring support portion configured to support an upper end of the sub-float biasing spring and a seal portion that is configured to come into contact with and separate from an opening portion. The main float is movable further upward with respect to the sub-float by compressing the sub-float biasing spring in a state where the float valve ascends and the opening portion is closed by the sub-float.

Abstract: There is provided an over-fueling prevention valve including a housing provided with a first opening, a second opening, and a first valve seat; a main valve provided with a one end opening, the other end opening, and a second valve seat; a first biasing portion; a sub valve; and a second biasing portion. Biasing forces of the first biasing portion and the second spring are set such that a valve re-closing pressure of the main valve is higher than a valve re-opening pressure of the sub valve. In a state in which the main valve is separated from the first valve seat, the first opening and the second opening communicate with each other via an external space.

Abstract: A damper includes: a piston configured to advance and retreat by receiving a force from another of a first member and a second member; a sliding member configured to slide on the piston as the piston advances and retreats; and a support member having a tubular portion and an insertion hole formed inside the tubular portion. The piston is inserted through the insertion hole. The sliding member includes a protruding portion protruding inward in a radial direction inside the tubular portion and configured to come into contact with an outer peripheral surface of the piston, an outer tubular portion disposed outside the tubular portion, and an extending portion extending inward in the radial direction from one end of the outer tubular portion and indirectly or directly coupling the protruding portion and the outer tubular portion.

Abstract: A holder for a long member includes: a holding member that includes a frame-shaped body portion; an anti-vibration member that includes a frame-shaped portion; and a fixing member that is provided with an insertion portion, and a flange. The anti-vibration member includes a pair of extension pieces that protrude in a state where the frame-shaped portion is inserted into the frame-shaped body portion, and that are sandwiched between the frame-shaped body portion and the flange when the insertion portion is inserted into the frame-shaped portion. Clearance is provided between an inner surface of a frame-shaped body portion side wall that faces a first wall in which the pair of extension pieces of the anti-vibration member are not provided in the frame-shaped body portion, and an outer edge of the flange facing the frame-shaped body portion side wall.

Abstract: There is provided a damper device including an annular elastic member made of an elastic resin material. One member of a pair of members is provided with a support section for supporting the annular elastic member. The other member of the pair of members is provided with a pair of facing walls between which the support section is to be inserted. The annular elastic member is provided with separated portions that are separated from the outer periphery of the support section. In a state where the annular elastic member is mounted on the outer periphery of the support section, a maximum distance A of the separated portions facing each other is greater than an opening width B between tip ends of the pair of facing walls on a side on which the support section enters.

Abstract: There is provided a valve device including: a housing; a float valve; and a pressure adjusting valve. A first valve seat is formed from a peripheral edge of a valve hole. An accommodation portion is provided in a protruding manner from a surface of a partition wall. An inner periphery of the accommodation portion is provided with a reduced diameter portion and an increased diameter portion. A height of an upper end of the reduced diameter portion is equal to or greater than a front surface of the pressure adjusting valve in a state where the pressure adjusting valve is in contact with the first valve seat. The pressure adjusting valve is configured to be beyond the upper end of the reduced diameter portion when the pressure adjusting valve is raised to a maximum due to an increase in pressure in a fuel tank.
