浅開孔６６の両端部FIELD OF THE INVENTION The present invention relates to a caliper support structure for a floating I7 liper type disc brake device used in small vehicles such as motorcycles and three-wheeled motorcycles. When the gear cylinder is positioned only on one side with respect to the smooth narrow disc plate, the friction pad member pushed by the caliper piston comes into contact with the disc plate, and the reaction force causes the caliper body to move. Four types of floating caliper type disc brake devices are well known. The floating caliper type disc play 1 device is normally movably supported by a vehicle body side member via a pair of sliding pin members. For example, one sliding pin member is screwed to the caliper body, and its tip side fits into a blind hole formed in the vehicle body side member so as to be freely retractable, and the other sliding pin member penetrates the caliper body. A caliper support structure similar to that in which the tips of A and A are screwed into the vehicle body side member is adopted. However, the fitting part between the sliding pin member and the vehicle body side member or caliper body, that is, the sliding surface, must always be maintained in a good surface condition. A sealing member (e.g., a rubber boot) is attached to the fitting part to prevent foreign matter such as rainwater, mud, and dust from entering, thereby preventing rust and wear on the sliding surface. In this way, it is extremely important to protect the sliding surfaces. ζ-! The present invention was created against this technical background,
The culprit is to partially reduce the frictional resistance of the sliding movement at the fitting part between the sliding pin member and the vehicle body side member or caliper body, and to reliably prevent rust from forming on the outer peripheral surface of the sliding pin member. There is a point of interest. In the V rib support structure of the disc brake device according to the present invention, the outer circumferential surface of the sliding pin part H that supports the 4" Yaripa body displaceably with respect to the vehicle body side member is coated with a resin having a thick friction coefficient. , the displacement of the first Yariba body due to braking is performed smoothly.An embodiment of the present invention will be explained below with reference to FIGS. 1 to 7. FIG. 1) A right side i-isk brake installation 22 of the 0th wheel is shown. .14 to 1 bolt
It is supported by a main sliding pin 36 and a sub-sliding pin 42 on a bracket 24 that is attached with 6.18. The main W#J pin 36 has a pair of circumferential grooves 3 as shown in FIG.
8.40, the two ends of which fit into the blind holes of the tongues 60, 62 which protrude from the caliper body 50 of the caliper 48 at a distance r from each other. Further, the main sliding pin 36 slidably passes through the main support hole 32 formed in the bracket 24. An outer circumferential groove 28.30 is formed on the outer periphery of both ends of the cylindrical portion 26 in which the main support hole 32 is formed, and a boot B1, which is a rubber cylindrical body, is formed in the circumferential groove 38 and the outer circumferential groove 28. A rubber boot B2 is similarly fitted into the circumferential groove 40 and the outer circumferential groove 30. The boots B and F32 protect the fitting surfaces between the main sliding pin 36 and the main support hole 32, as well as the sliding surfaces of both, from foreign matter such as rainwater, mud, and YA. The sub-sliding pin 42 is a hexagon socket head bolt, and the
) 1ii11 with one end formed in brackets 1 to 24
It is screwed into the support hole 34, and the head side, which is 14 feet longer than the threaded part, is shaped like a circular hand. Bren (Pth) is covered with a double film (film 46), 1 this covering F

)'M The rib 86 of the sealed envelope 84 is fitted, and the rib 88 is along the outer edge of the opening 66. is in close contact with the outer periphery of the cylindrical portion 44 of the sub-sliding bottle. Then, the rib 92 of the sealing lid 90 made of polyamide (trade name, nylon 6), which has two ribs 92 and 94 on the cylindrical outer periphery of Ll, is fitted to the inner circumferential groove 70. along the outer edge of the aperture 66. The sealed envelope 84 and the sealed lid 90 work together to protect the fitting surfaces of the sub-sliding bottle 42 and the opening 66, that is, the sliding surfaces of both, from foreign substances such as rainwater, dirt, and dust. Above, Figure 3,
(See Figure 4). Note that the sealed envelope 84 and the sealed lid 90 are not limited to polyamide, and may be made of rubber or other resin materials. Further, the caliper body 50 of the Kitripa 48 is obtained by connecting a pair of half-holes 52 and 56 at a joining surface 58 and joining them together with a pair of connecting bolts 74 and nuts 76.
1 to 3), the main sliding pin 36 is therefore inserted into the blind hole in the tongue 60.62 before joining the two halves 52.56. A pair of Kireripa cylinders 54 are
The caliper piston 72 is formed into a half body 52, and a caliper piston 72 is fitted into and retractably into the V lip ring 54. The half-rest 56 is formed as a pawl member that straddles the outer side of the disc plate D that is screwed and fixed to the wheel hub 20. In addition, a pair of friction pad members 80.82, which are slidably supported by hanger pins 18 inserted from the half body 56 side toward the half body 52, are provided in a space defined by the half body 52.56. Part (Disc play 1-

When disk plate D is rotating in the direction of the arrow (7
iNarichi, while driving), operating Ki17 Ripa 48, etc.
The caliper piston 72 moves forward and pushes the back surface of the friction pad member 80 that is in contact with C1, pressing it against the disc plate D, and the reaction force causes the caliper body 50 to move between the main sliding pin 36, the main support hole 32, and the sub-sliding pin. 42 hole 66,
Under each slidable fitting relationship, the super surface is displaced to the front side in FIG. 2 or to the left in FIGS. 2 and 3,
Friction pad 82 is also pressed against the opposite surface of disk plate D. Since the outer circumferential surface of the cylindrical portion 44 in the sub-sliding bin 42 is coated with a resin coating 46 having a low coefficient of friction, sliding within the opening 66 is smooth and the caliper body is damaged during braking. smooth displacement is guaranteed. The coating 46 not only improves the sliding properties of the sub-sliding pin 42, but also has the function of damping vibrations of the sub-sliding pin 42 within the aperture 66 and preventing noise generation. In addition, the fitting part between the secondary 1st learning bottle 42 and the opening 66 is protected from rainwater, mud, and dust by a sealed envelope 84 and a sealed lid 90, and in addition, the outer periphery of the cylindrical part 44 is covered with a coating 46. Since it is covered, rusting and friction on the friction surfaces are effectively suppressed, and in this respect, smooth displacement of the caliper body 50 is guaranteed over a long period of time. Furthermore, the structure in which the head of the sub-sliding pin 42 is formed to have the same diameter as the columnar part 44 and the sealing lid 90 is attached to the tongue piece 64 has a structure in which the entire length of the sub-sliding pin 42 is the same as that of the conventional one (when the boot is attached). The length of the caliper 48 is significantly shorter than that of the conventional caliper 48, which can contribute to reducing the weight of the caliper 48. Note that the peeling resistance of the coating 46 is improved by forming it as a thin film. Further, in this embodiment, the resin coating is applied only to the sub-sliding pin 42, but it can also be applied to the main sliding pin 36. As is clear from the above explanation, in this defense, the outer peripheral surface of the sliding bottle member that supports the caliper body in a movable manner relative to the vehicle body side member is coated with a resin having a low coefficient of friction. ,
Smooth displacement of the caliper body is maintained during braking, and it is possible to prevent rusting of the sliding pin member and to provide vibration and soundproofing effects in the sliding portion.
