摘要： A bearing bush, disposed in a shaft hole of an external gear of a seat reclining device, which slidingly contacts wedge-shaped pieces. The seat reclining device has a differential transmission mechanism for adjusting an open angle of a hinge connecting a seating surface of a seat and a backrest thereof to each other. The differential transmission mechanism has an internal gear; an external gear, having a smaller number of teeth than the internal gear, which engages the internal gear; a pair of the wedge-shaped pieces disposed in a circular arc-shaped gap formed between the shaft hole of the external gear and a shaft of the internal gear with tapered ends of the wedge-shaped pieces opposed to each other; and a compression coil spring for imparting an elastic force to the wedge-shaped pieces in a direction in which the wedge-shaped pieces depart from each other. When the wedge-shaped pieces are moved in sliding contact with the bearing bush inside the circular arc-shaped gap with the wedge-shaped pieces being pressed by a cam provided on the shaft of the internal gear, the external gear disengages from the internal gear, whereby the open angle of the hinge is adjustable. A sliding surface of the bearing bush is formed of a fluorocarbon resin composition containing fluorocarbon resin to which thermoplastic resin, carbon fibers, and molybdenum disulfide are essentially added.

摘要： A method for manufacturing a plate-shaped peeling member having a thin metal plate and a resin sheet adhered thereto by winding the resin sheet around a leading edge of the thin metal plate. The plate-shaped peeling member peels paper from a roller or a belt of an electrophotographic apparatus, with a leading edge of the thin metal plate in contact with or being adjacent to the roller or the belt. The method includes the steps of stacking an adhesive agent-applied resin sheet to one main surface of a thin metal plate without pulling both end portions of the adhesive agent-applied resin sheet in a longitudinal direction thereof, with an unstuck portion left on the adhesive agent-applied resin sheet in a widthwise direction thereof and with the adhesive agent-applied resin sheet being pressurized in a longitudinal direction thereof; temporarily sticking the unstuck portion left on the adhesive agent-applied resin sheet in the widthwise direction thereof to other main surface thereof by folding back the unstuck portion along a leading edge of the thin metal plate toward the other main surface thereof without pulling the both end portions of the adhesive agent-applied resin sheet in the longitudinal direction thereof; and fixing the temporarily unstuck portion of the adhesive agent-applied resin sheet to the other main surface of the thin metal plate, while the unstuck portion is being pressurized in the longitudinal direction of the adhesive agent-applied resin sheet from approximately a center of the adhesive agent-applied resin sheet in the longitudinal direction thereof.

摘要： A slide bearing is proposed which rotatably supports a rotary shaft of an impeller in a cooling water circulation pump mounted to a fuel cell. The slide bearing is formed of a synthetic resin containing no metal ions such as polyetherketone resin. This prevents impurities originating from the slide bearing from being dissolved into cooling water for the fuel cell.
