本発明はビンタイプディスクブレーキの滑動支持装置の
改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sliding support device for a bin type disc brake.
一般にビンタイプディスクブレーキは、ローター縁部を
跨ぐように配設されたキャリパ又は車体と一体の固定支
持体のいずれか一方に形成された開口に対し、前記キャ
リパ又は固定支持体のいずれか他方に組付は固定したス
ライドビンを嵌押滑合させることにより構成されて、前
記キャリパを固定支持体に対しローター佃（方向移動可
能に支持させるものが普通である。Generally, in a bin-type disc brake, an opening is formed in either a caliper disposed to straddle the edge of the rotor or a fixed support integral with the vehicle body, and an opening is formed in the other of the caliper or fixed support. The assembly is usually carried out by fitting and sliding a fixed slide bin, and the caliper is supported movably in the rotor direction (directionally movable) with respect to the fixed support.
ところでこのよう々滑動支持装置では、これがローター
の周方向に隔役して対をなすように設けられることから
、そのピッチ寸法の公差を吸収するなどのために開口と
スライドビンの滑合面の間にゴムブツシュを嵌合させる
のが普通で、寸たこのゴムブツシュには、スライドビン
の開口から延出している面を外気から封止する如く被チ
するブーツ部を一体化あるいは絹付けるようにしている
ものも多く知られている。By the way, in such a sliding support device, since these are provided in a pair separated in the circumferential direction of the rotor, the sliding surface of the opening and the slide bin should be adjusted to absorb the tolerance of the pitch dimension. Usually, a rubber bushing is fitted in between, and a covering boot part is integrated or attached to the rubber bushing so as to seal the surface extending from the opening of the slide bin from the outside air. Many are known to exist.

のブーツ部４Ｃは、スライドビン２の自由端を包む袋形
状をなしてスライドビン２を覆っている。However, with this configuration, there is a problem that the boot portion may be damaged by flying stones while the vehicle is running, or the boot or bushing may be cut due to twisting of the slide bin and the opening when replacing the pad. FIG. 1 shows an example of such a conventional configuration, where 1 is a fixed support and 2 is this fixed support 1.
3 is a rubber bush that is fixedly fitted to the inner circumferential surface of the opening 3 of the caliper boss, and the opening 3 of the caliper is fixed by a recess 4a on the outer periphery. It is fitted across both ends of the IC. 4
b and 4c are boot parts integrally extended from both ends of this rubber bush 4, while 4b is a bellows-shaped body with a telescopic thread that extends around the outer circumferential surface of the slide bin 2;
The end portion is tightly secured to the outer circumferential groove 2a. The other boot portion 4C has a bag shape that wraps around the free end of the slide bin 2, and covers the slide bin 2.
そして、これらブーツ部４ｂ、４Ｃが飛石等により破損
されると、滑合面の外気からの封止が解除されてしまう
ことになるし、スライドビン２の自由端部がブーツ４Ｃ
に当ってパッド交換作業の際にその破損を生ずることが
考えられるのである。If these boot parts 4b and 4C are damaged by flying stones or the like, the sealing of the sliding surfaces from the outside air will be released, and the free end of the slide bin 2 will be damaged by the boot 4C.
It is conceivable that damage may occur during pad replacement work.

ブレーキの滑動支持装置にある。Therefore, in the present invention, problems such as damage to the boot part caused by flying stones are reduced as much as possible by the relative movement, and furthermore, by wrapping the free end of the slide bin in a bag shape, there is no particular need for an expandable part such as a bellows. The boot portion is made of a rigid material to reduce the risk of the rubber boot being damaged by flying stones or the corners of the end of the slide bin. The gist of the present invention is to provide an opening formed in either the caliper disposed to straddle the edge of the rotor or the fixed support fixed to the vehicle body. A sliding support device in which a slide bin fixed in a cantilever manner passes through the opening and supports the caliper so as to be movable in the rotor axial direction, and the opening has a free end of the slide bin in a bag-like shape. This sliding support device for a disc brake is characterized in that a protector made of a cylindrical rigid body with one end open in the shape of a wrapper is fitted, and a rubber boot is installed across the open end of the protector and the outer periphery of the slide bin.
