Description of the Related Art A slide pin attached to one of a caliper or a support bracket of a disc brake is slidably fitted in a pin guide hole provided in the other of the caliper or the support bracket. A cylindrical bearing having a C-shaped cross section is fitted in the pin guide hole in order to reduce the sliding resistance of the pin guide hole and to prevent the abrasion thereof. Various stoppers are provided to prevent the bearing from slipping out of the pin guide hole. As one of the retaining means, there is adopted a means in which an annular groove is provided on the inner surface of the pin guide hole and a so-called snap ring is fitted in the annular groove, which is generally adopted. By the way, any of the conventionally known retaining means requires special processing for that purpose, special work for assembling them, and labor. If the retaining mechanism for the bearing is installed at the same time as mounting the bearing in the pin guide hole or assembling the slide pin in the pin guide hole, labor saving and efficiency of the assembling work can be achieved. Further, if the mechanism of the retaining means can be devised so that the retaining means can be mounted without applying special processing to the pin guide hole, the processing cost can be reduced accordingly.

The bearing is prevented from coming off. Normally, as the bearing, an oilless bearing having a plastic C-shaped cross section such as a synthetic resin reinforced with a metal mesh or a synthetic resin reinforced with a reinforcing fiber such as glass fiber is used. After mounting in the pin guide hole, press fit a jig (adjustment pin) with a diameter larger than the inner diameter of the bearing to expand the bearing to the specified inner diameter, and set the clearance between the slide pin and the bearing to the specified size. Adjust accurately. This work is conventionally performed as a bearing assembly work.
If a step is provided on the above jig, a washer with external teeth is previously attached to the pin portion to be inserted into the bearing, and this jig is press-fitted into the bearing inserted into the pin guide hole, the external tooth with The washer hits the stepped portion of the jig and is pushed into the counterbore hole, press-fitted into the counterbore hole, and fixed in the counterbore hole. Therefore, at the same time as the work of assembling the bearing, the bearing is prevented from coming off. The counterbore is provided in the end surface of the support bracket as a hole for fitting the bearing flange, but the counterbore in the present invention is a counterbore to the extent that an external toothed washer can be fitted. The counterbore is slightly deeper than the conventional counterbore.

る。[Examples] Next, examples will be described with reference to the drawings. The bearing 1 of this embodiment is a C-shaped bearing made of synthetic resin which is reinforced by a metal mesh and is self-lubricating and has high wear resistance, and has an inner diameter of about 9,5 mm before being mounted in the pin guide hole. The outer diameter is 10, 5 mm, and the inner diameter of the pin guide hole 3 of the support bracket 2 is 10, 5 mm. The adjusting pin 5 of the jig 4 for expanding the bearing 1 with the bearing 1 inserted in the pin guide hole 3 and adjusting the inner diameter thereof.
Has an outer diameter d of 9 and 8 mm, and the outer diameter D of the main body of the jig 4 is
Is 15 mm. Therefore, the step portion 6 is formed between the adjusting pin 5 and the main body portion. The outer diameter of the flange 1a of the bearing is 14, 5 mm, the inner diameter of the counterbore 7 is 18 mm, and the depth h of the counterbore 7 is 3 mm. further,
The inner diameter of the washer 8 with outer teeth is 10 mm, and the outer diameter of the outer teeth 9 is 1
It is 8, 2 mm, the thickness is 0, 4 mm and the tooth height is about 2 mm. The depth of the counterbore is preferably 2 to 3 mm larger than the sum of the thickness of the flange and the thickness of the washer with external teeth. In the above embodiments, the adjustment pin 5 of the jig 4 is preliminarily attached with the washer 8 with external teeth, and the adjustment pin 5
Is press-fitted into the bearing 1 mounted in the pin guide hole 3. At this time, the stepped portion 6 of the jig 4 pushes the external toothed washer 8 into the counterbore hole 7 and the flange 1a. As a result, the washer 8 with external teeth is press-fitted into the counterbore 7, the external teeth 9 are deformed outward, and their edges bite into the inner surface of the counterbore to be fixed. At this time, the bearing 1 is expanded by the adjusting pin 5 and the inner diameter thereof is adjusted to approximately 9 and 8 mm.

ことも本発明の大きな利点である。[Effect] The invention which has solved the problems of the present invention is not yet known. Therefore, solving this problem and solving the above-mentioned problems of the conventional technique is an effect peculiar to the present invention. That is, it is possible to omit special machining such as groove processing for mounting the slide pin bearing retaining means, and to expand the bearing so that the gap between the slide pin and the bearing inner surface has a predetermined size. Since the external toothed washer, which is the retaining means, can be mounted at the same time by the work of press-fitting the adjusting pin of the jig for adjustment into the bearing, a special operation for mounting the retaining means can be omitted. Therefore, the processing cost and the assembly work cost can be reduced. Also, with this washer with external teeth, the flange of the bearing can be firmly fixed to the bottom surface of the counterbore hole, and the washer with external teeth is firmly fixed to the inner surface of the counterbore hole. The fixing to the bearing flange does not loosen, so that the bearing can be rigidly fixed to the pin guide hole of the fixing member. This is also a great advantage of the present invention.
