A valve seat is provided on a lower surface side of the partition wall, and plural radially-extending thin ribs are formed therearound. Plural axially-extending check valve guide ribs are provided at predetermined circumferential intervals with in the vent chamber R2, and plural axially-extending float valve guide ribs are provided at predetermined circumferential intervals within the valve chamber R1. The thin ribs and the check valve guide ribs are formed circumferentially alternately so as not to be superposed on each other when viewed from an axial direction of the housing.
Abstract: A damper apparatus includes a piston having a flange-shaped piston main body and piston rods which project from both ends of the piston main body, a cylinder having a cylinder main body which accommodates the piston main body slidably and cylindrical portions which support slidably the piston rods, respectively, a fastener which is attached to the one cylindrical portion so as to secure the cylinder to an opening/closing member, and a coil spring which biases the one piston rod to project from the other cylindrical portion such that a distal end portion of the piston rod abuts a circumferential edge of an opening portion of a vehicle.
Abstract: A supporting projection is formed on a resin base plate on which a seat winding portion of a coil spring is fitted. The supporting projection has such rigidity that a distal end portion does not deflect against a spring force applied radially inwards from the seat winding portion of the coil spring. On the other hand, an elastic deflectable area which deflects elastically by the spring force applied radially outwards from the seat winding portion of the coil spring is formed in an area which extends from a proximal end to the distal end portion of the supporting projection.
Abstract: A pressing device is provided with a pin member, a coil-like spring member, and a spring receiving member which has a through-hole for allowing the pin member to be inserted therein and which supports one end of the spring member. The pin member has: a shaft section which has the spring member disposed on the outer peripheral side thereof; a head section which is interconnected with one end of the shaft section and which can come into contact with the contact surface of the opening/closing body; a spring support section which supports the other end of the spring member; and an engagement claw which engages with the outer surface of the mounting portion and which prevents the pressing device from being dislocated from the mounting portion.
Abstract: A sun visor holder includes a main body section to receive the shaft and a leg section to engage with the inner wall of the vehicle. A first engaging piece is formed with the tip side of the leg section as a fulcrum so as to be bendable inward, includes a release section that extends outward along the mounting surface of an inner wall from the free-end side of said first engaging piece, and is configured so that pressing the release section from the surface side of the inner wall causes the first engaging piece to bend inward and engagement with a mounting hole is released.
Abstract: A member mounting structure joins together a first member which has a first mounting hole and a second member which has a second mounting hole. The member mounting structure is configured in such a manner that a pin has a shaft section and a radial protrusion section which protrudes in the radial direction from the shaft section. A clip, which is formed by punching and press-forming a metallic plate and which is used to grip the first member, has: a first plate section which has formed therein a first insertion hole into which the shaft section of the pin is inserted; a second plate section which faces the first plate section; and a connection section which connects the first plate section and the second plate section.
Abstract: A spring assembly includes a substrate, an inner coil spring, and an outer coil spring arranged outside the inner coil spring. One of the inner coil spring and the outer coil spring includes an end turn portion, the end turn portion forming a support wall for an other of the inner coil spring and the outer coil spring.
Abstract: In a damper, a case member has a body, a flange formed at one end of the body, and a bottom formed at the other end of the body. A pin member has a head, that protrudes from an opening of the flange and a shaft that is connected to the head and has a stopper on an end thereof. The bottom has a retaining hole, into which the tip of the shaft is inserted, for stopping the stopper. The body has locking claws, for sandwiching the rim of the mounting hole against the flange.
Abstract: An overfill prevention valve includes: a valve housing having a first valve seat communicating with a fuel tank, and a second valve seat communicating with a canister; a parent valve disposed slidably within the valve housing, and having a base end opening communicating with a first opening, a front end opening communicating with a second opening and a third valve seat provided in the base end opening; a first urging unit which urges the parent valve toward the first valve seat; a child valve disposed slidably within the parent valve; a second urging unit which urges the child valve toward the third valve seat; and an air passage forming unit which forms an air passage between the parent valve and the first valve seat when the patent valve abuts on the first valve seat.
