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: A damper includes a cylinder, a rod including a first engaging portion at a tip end thereof, and a piston formed of an elastic resin material. The piston includes a convex portion provided so as to protrude at a base end portion located on a rod base end side and always in pressure contact with an inner circumference of the cylinder. During damper braking, the first engaging portion of the rod abuts against the other end portion of the piston, and an axial compression force acts on the piston between the first engaging portion and the convex portion in pressure contact with the inner circumference of the cylinder.

Abstract: A part fixture which is locked on a locking portion of a vehicle body and which is inserted into a mounting hole on a mount portion provided on a vehicle body to be fixed in place therein to thereby mount the vehicle part on the mount portion, includes an accommodating portion, a locking piece, a pair of flange portions, and a pair of elastic engaging pieces. The elastic engaging pieces each have an engaging claw and an operation knob. When the pair of elastic engaging pieces are deflected inwards of the accommodating portion, the pair of elastic engaging pieces are brought into abutment with the side wall portions or the locking portion of the vehicle part which is accommodated in the accommodating portion so that any further deflection thereof is restricted.

Abstract: A stopper device includes: a stopper that has an abutting part located at a distal end of a tubular part in the axial direction, and a through-hole penetrating through the abutting part and communicating with the inside of the tubular part; and a screw that has a flange-shaped screw head accommodated in the tubular part, and a shaft projecting toward a proximal end side of the tubular part in the axial direction. The tubular part has a first restricting part that restricts movement of the stopper toward the distal end in the axial direction by being engaged with the screw head. The position of the stopper in the axial direction is changed by inserting a tool in the tubular part through the through-hole and rotating the screw.

Abstract: There is provided a holding device mounted in a mounting hole in a mount member to hold a predetermined member. A base member is mounted in the mounting hole. A bag hooking member is supported rotatably on the base member. The bag hooking member has a holding portion that takes, depending on its rotational positions, a protruding state and a stowed state and that holds the predetermined member in the protruding state. The base member has a frame portion surrounding the bag hooking member, a claw portion extending from one side of the frame portion to be locked on a rear side portion of the mount member, and an erect portion erected from the one side of the frame portion to be locked on the rear side portion in a position lying nearer to the mounting hole than a distal end of the claw portion.

Abstract: According to one embodiment, a hose clamp has a leaf spring body, a slit and a first knob piece at one end, and an insertion piece and a second knob piece at the other end. An interlocking piece is formed in the first knob piece, and an engaging holding part is formed in the second knob piece. When the hose clamp is viewed from the outside in the radial direction while the leaf spring body is in a free state of being compressed, the first knob piece and the second knob piece are extended outward in the width direction so as to be separated.
