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 the 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 periphery of the flange, inner and outer peripheral engaging parts 35 and 36 formed on the inner and outer peripheral surfaces of the ends of the annular protrusion, and formed on the upper surface of the flange. substantially cylindrical bearing portion 37, and the bearing body 40
A disc-shaped part 42 having a circular hole 41 in the center, a cylindrical bearing part 43 formed on the lower surface of the disc-shaped part, and an annular groove 44 separated from the inner circumferential surface of the bearing part, and the tip of the disc-shaped part 42 is connected to the bearing part. an annular protrusion 45 that protrudes from the end face of the bearing part and is continuous with the circular hole 41; The bearing body 40 includes a hanging part 47 and an engagement step part 48 formed on the outer peripheral surface of the hanging part, and the bearing body 40 has an end face of the cylindrical bearing part 43 in sliding contact with an end face of the substantially cylindrical bearing part 37 of the case flange part. , the ends of the annular protruding part 45 and the annular hanging part 47 are made to protrude from the end surface of the bearing part, respectively, and the engaging step part 48 on the outer peripheral surface of the annular hanging part 47 is connected to the inner peripheral engaging part 35 of the annular projecting part of the case. The bearing body 40 is elastically attached and combined with the case so as to be relatively rotatable.
On the upper surface of the disk-shaped portion 42, there is a reinforcing disk 52 having a circular hole 51 in the center, a cylindrical portion 53 that hangs down to cover the upper surface of the disk and the outer peripheral surface, and an inward portion at the tip of the cylindrical portion. An elastic seal body 50 made of a rubber elastic body and having an annular lip portion 54 that narrows at the bottom is disposed so that the annular lip portion 54 is brought into close contact with the outer peripheral engagement portion 36 of the annular protrusion portion 34 of the case. Synthetic resin thrust bearing.
