Claims

[Scope of utility model registration request]

The case 3 consists of a synthetic resin case 30 and a synthetic resin bearing body 40 that is slidably fitted into the case.
0 is a cylindrical part 32 having an insertion hole 31 on its inner surface, and a wide flange part 3 integrally formed on the outer peripheral surface of the end of the cylindrical part.
3, an annular protrusion 34 integrally formed on the outer peripheral edge of the flange, an engagement step 35 formed on the outer periphery of the annular protrusion, and a substantially cylindrical bearing 3 formed on the upper surface of the flange.
6 and an annular convex portion 37 formed on the inner peripheral edge of the bearing portion so as to be continuous with the inner peripheral edge and protrude from the end face of the bearing portion, and the bearing body 40 has a circular hole 41 in the center thereof. 42 , a cylindrical bearing portion 43 formed on the lower surface of the disk-shaped portion, and an annular groove 44 separated from the inner peripheral surface of the cylindrical bearing portion, with the tip thereof protruding from the end surface of the bearing portion, and into the circular hole 41 . An annular inner protrusion 45 which is formed continuously, an annular outer protrusion 47 which is formed by separating the outer peripheral surface of the cylindrical bearing part from the annular groove 46 and whose tip protrudes from the end face of the bearing part, and the disc-shaped part. Part 4
The bearing body 40 has an annular hanging part 49 formed on the outer peripheral edge of the case 2 and having an engaging hook part 48 at the tip thereof, and the bearing body 40 slides the end face of the cylindrical bearing part 43 into the end face of the substantially cylindrical bearing part 37 of the case flange part. annular inner and outer protrusions 4
5 and 47 are respectively projected from the sliding end surfaces of the cylindrical bearing parts 37 and 43, and the engagement hook part 48 at the tip of the annular hanging part 49 is connected to the engagement step part 3 of the case.
5. A synthetic resin thrust bearing characterized in that the synthetic resin thrust bearing is elastically attached to the base plate 5 and combined so as to be relatively rotatable.
