Claims

[Claims for Utility Model Registration] (1) It consists of a synthetic resin case 21 and a synthetic resin bearing body 22 that is slidably fitted into the case, and the case 21 has a cylindrical part 24 having an insertion hole 23 on the inner surface. A first annular lower lip portion 25 having an inner diameter increasing with the insertion hole and a stepped portion on the upper end surface of the cylindrical portion; and a wide flange portion 26 integrally formed on the outer peripheral surface of the end portion of the cylindrical portion. An annular protrusion 27 integrally formed on the outer peripheral edge of the flange, an engaging portion 28 formed on the outer periphery of the annular protrusion, and a first annular protrusion formed concentrically with the insertion hole on the upper surface of the flange The bearing body 22 is provided with a second annular lower lip part 30 that defines an annular groove 29 with an annular lower lip part, and the bearing body 22 is integrally formed with a cylindrical bearing part 31 at the upper end of the inner circumferential surface of the cylindrical bearing part. An annular collar portion 32, a first annular upper lip portion 33 extending downward integrally formed on the peripheral edge of the annular collar portion, a flat portion 34 integrally formed on the upper end of the outer peripheral surface of the cylindrical bearing portion, and the flat surface. An annular hanging part 35 integrally formed on the periphery of the part, an engaging hook part 36 formed at the lower end of the hanging part, and a second part formed concentrically with the cylindrical bearing part on the lower surface of the flat part 34. An annular upper lip portion 37 is provided, and the bearing body 2
2 elastically attaches the engaging hook portion 36 of the annular hanging portion 35 to the engaging portion 28 of the case 21, and connects the ends of the first and second annular upper lip portions to the first and second annular portions of the case, respectively. It is combined with the lower lip part so as to overlap in the radial direction so as to be relatively rotatable, and sealing parts by labyrinth action are formed in the elastic mounting part and the first and second annular upper and lower lip parts, respectively. Inside the case is a cylindrical bearing part 31 of the bearing body.
A synthetic resin thrust bearing characterized in that the lower surface is placed in sliding contact with the bottom surface of the annular groove 29. (2) An engaging hook portion 41 is formed at the end of the first annular upper lip portion 33 of the bearing body, and an engaging portion 40 is formed on the inner peripheral surface of the first annular lower lip portion 25 of the case. 2. The synthetic resin thrust bearing according to claim 1, wherein the two are elastically mounted and combined so that they can rotate relative to each other.
