Abstract: The nut of the present invention is an encased nut including: a case body which is welded to a body; and a nut which is freely movably held inside the case body. The nut is composed of a hexagonal nut body and an insulating member made of a resin and insert-molded on the outer surface of this hexagonal nut body. The insulating member is provided with a plurality of protrusions on the side, abutting on the body, of the outer circumferential part. The nut is insulated, and thus is not affixed by electrodeposition coating.

Abstract: The nut of the present invention is an encased nut including: a case body 2 which is welded to a body 1; and a nut 3 which is freely movably held inside the case body 2. The nut 3 is composed of a hexagonal nut body 4 and an insulating member 5 made of a resin and insert-molded on the outer surface of this hexagonal nut body 4. The insulating member 5 is provided with a plurality of protrusions 9 on the side, abutting on the body 1, of the outer circumferential part. The nut 3 is insulated, and thus is not affixed by electrodeposition coating.

Abstract: A seal washer of the present invention includes a metal washer body including a center hole, an outer resilient material projecting from an outer periphery of the washer body to a location lower than a lower surface of the washer body, and an inner resilient material provided on an inner periphery of the washer body which faces the center hole. If a fastening force in an axial direction is applied, since the lower surface of the washer body metal-touches on a mating member, loosening does not occur unlike a conventional technique. In addition, since no further compression load is applied to the resilient material, a phenomenon that the resilient material is deformed in a crushed manner does not occur.

Abstract: A resin bracket comprising a mount portion mounted to a member being mounted and an extending portion extended from the mount portion, wherein a ball joint with a substantially spherical-shaped portion is provided integrally on the extending portion. An opening/shutting mechanism having two resin brackets, wherein each of brackets is mounted members being mounted to be opened and closed.

Abstract: A fastening position adjustable bolt is provided which includes a bolt body and a cylindrically shaped collar bolt. The bolt body has a head, a shank, and first male threads formed on a lower outer peripheral surface of the shank, and the collar bolt has second male threads formed on an upper outer peripheral surface thereof. An engaging portion engages the shank of the bolt body with the collar bolt. The engaging portion is disposed between the head of the bolt body and a position on the shank at which the first male threads are formed, and the engaging portion is adapted to release engagement between the collar bolt and the shank of the bolt body upon application of a torque having at least a predetermined value.

Abstract: A water-proof grommet is provided which includes a plate-shaped head, a polygonal grommet body, and at least two latch pawls connected at lower ends to the grommet body and arranged on an outside surface of a substantially central portion of the grommet body. The head is substantially flat at a back surface thereof, and the latch pawls are provided at tip end portions with at least one inclined surface inclined outward and downward from the grommet body and at least one adjacent flat portion. The grommet body is adapted to expand radially as a screw is threaded therein, so as to cause an outer surface of the grommet body to deform the latch pawls radially outward and thereby cause at least one of the inclined surface and the adjacent flat portion of the latch pawls to press a member being mounted toward the back surface of the head.

An opening/shutting mechanism having two resin brackets, wherein each of brackets is mounted members being mounted to be opened and closed.

Abstract: The invention has been contrived to solve the above-mentioned problems of the prior grommets and to provide a water-proof grommet, in which insertion load can be reduced further than those of the prior grommets and an entire grommet is not moved axially irrespective of plate thickness of a member being mounted.

Abstract: There is disclosed a guide slider for a window regulator that does not cause to rise an allophone, a awkward movement and a jolt to a rail in which said guide slider is made a slidable movement, wherein said guide slider comprises a substantially lod blank having a substantially spherical head at one tip end thereof and a main body of guide made of thermoplastic resin, wherein further the main body of guide has a receiving and bearing seat in which the head of the blank can be received in such a manner that the axis of the blank becomes coaxial to that of the main body of guide, and the receiving and bearing surface of the main body of guide closely contacts with the surface of the head but the slidably rotational movement of the head in the receiving and bearing seat is permitted.

Abstract: A spare tire-fixing device comprises a rod-shaped clamping member (1) having a screw (2) at the lower end thereof and a head (3) at the upper end thereof, respectively; and a substantially disc-shaped tire presser (10) having a shaft tube (11) having first and second circular bearing seats (11a, 11b) as both end faces thereof and a center hole into which the screw of the clamping member can be inserted, at the center thereof, and a collar (12) which is a doughnut-shaped member linked with the shaft tube via a peripheral frame (13) in the outer peripheral direction of the shaft tube and has first and second tire-pressing faces (12a, 12b) as both end faces thereof, respectively, wherein a difference in level corresponding to the difference between the width of a normal tire and that of a temporary tire is provided between the shaft tube and the collar.
