ことを特徴とする合成樹脂スラスト軸受。 Consisting of a synthetic resin case 21 and a synthetic resin bearing body 22 that is slidably fitted into the case, the case 2
1 includes a cylindrical part 24 having an insertion hole 23 on the inner surface, a wide flange part 25 integrally formed with a part 24a of the cylindrical part protruding from the outer circumferential surface of the end of the cylindrical part, and a wide flange part 25 integrally formed on the outer periphery of the flange part. An annular protrusion 26 formed on the annular protrusion, an engaging portion 27 formed on the outer peripheral surface of the annular protrusion, and a partial protrusion of the cylindrical portion formed on the upper surface of the collar concentrically with the insertion hole. The bearing body 22 is provided with an annular lower lip portion 29 defining an annular groove 28, and the bearing body 22 is connected to the cylindrical bearing portion 3.
0, an annular collar portion 31 integrally formed on the upper end of the inner circumferential surface of the cylindrical bearing portion, a flat portion 32 integrally formed on the upper end of the outer peripheral surface of the cylindrical bearing portion, and an annular collar portion 32 integrally formed on the periphery of the flat portion. An annular hanging part 33, an engagement hook part 34 formed at the lower end of the hanging part, and an annular upper lip part 35 formed on the lower surface of the flat part 32 concentrically with the cylindrical bearing part. 22 elastically attaches the engaging hook part 34 of the annular hanging part 33 to the engaging part 27 of the case 21, and causes the end of the annular upper lip part to overlap with the annular lower lip part of the case in the radial direction to achieve relative rotation. In addition, the elastic mounting portion and the upper and lower lip portions are each formed with a sealed portion by a labyrinth effect, and within the case, the cylindrical bearing portion 30 of the bearing body has its lower surface connected to the upper surface of the flange portion. A synthetic resin thrust bearing characterized in that it is disposed in sliding contact with the bottom surface of an annular groove 28.
