本発明は、車両等のブレーキあるいはクラッチマスクシ
リンダ用として好適な作動液リザーバに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hydraulic fluid reservoir suitable for use in a brake or clutch mask cylinder of a vehicle or the like.
この種の作動液リザーバは、作動液を貯える容器（リザ
ーバ本体）内に作動液を貯え、作動液が開口部から漏出
しないようにシールしてキャップで蓋をするが、このよ
うな容器として、従来、実公昭４９−２６０４７号公報
に記載されたものがある。This type of hydraulic fluid reservoir stores hydraulic fluid in a container (reservoir body), which is sealed and covered with a cap to prevent the hydraulic fluid from leaking from the opening. Conventionally, there is one described in Japanese Utility Model Publication No. 49-26047.
ここに開示されている容器は容器本体の開口部に該開口

）に開弁し、又は逆の場合にも開弁する。The container disclosed herein is sealed by attaching a cap to the opening of the container body with a sealing material interposed therebetween that covers the entire opening, and fixing the outer periphery of the sealing material between the cap and the opening. However, a slit is formed in the deformable plate portion of the sealing material in order to allow the internal space in the container body that stores the hydraulic fluid to breathe. This slit opens when the pressure in the internal space becomes lower than the pressure in the space between the sealing material and the cap (negative pressure), or vice versa.
キャップでシール材の外周部を開口部との間に挟圧して

うに変形して、板部に設けである上記スリットが開いた
ままになったり、あるいは開弁圧が高くなったりし、上
記スリットの正常な開閉動作が失われることが起こる。In the conventional structure in which the sealing effect is obtained by compressing the outer circumference of the sealing material between the cap and the opening, when the cap is rotated relative to the opening and assembled to the container body, the seal is damaged due to friction. The outer periphery of the material is twisted, and due to the twisting of the outer periphery, the plate part of the sealing material is deformed so that it twists or twists, and the slit provided in the plate part remains open. Or, the valve opening pressure may become high, and the normal opening/closing operation of the slit may be lost.

的とする。The present invention has been made to solve the above problem, and when the cap is attached, the twisting of the outer circumference is blocked from the slit side of the sealing material by the rotational force and frictional force that act on the outer circumference of the sealing material, and the cap is attached. The purpose is to provide a hydraulic fluid reservoir that can ensure the normal functioning of the subsequent slit.
本発明は上記目的を達成するため、シール材の板部に設
けるスリットと外周部との間に環状の薄肉部を形成する
ようにしたものである。In order to achieve the above object, the present invention is such that an annular thin section is formed between the slit provided in the plate section of the sealing material and the outer peripheral section.
［作用〕

れる。[Function] In the present invention, since an annular thin wall portion is provided between the plate portion of the slit and the outer peripheral portion which is clamped and fixed between the cap and the main body opening, the above-mentioned problem occurs when the cap is rotated and attached. The effect of twisting acting on the outer circumferential portion is absorbed by the deformation of this thin wall portion, and even if the outer circumferential portion of the sealing material is twisted by the rotational force received from the cap, deformation of the slit portion is prevented.

突部２９ｂが形成されている。The above-mentioned cap seal 29 is formed using an elastic material such as rubber, and has a brim-like outer peripheral part 29B on the outer periphery of the plate part 29A, as shown enlarged in FIGS. 4(a) and 4(O). The overall shape is a shallow dish, and the plate portion 29
A slit 29C is formed in the center of A. An annular thin wall portion 29D is formed near the outer peripheral portion 29B of the plate portion 29A of the sealing material 29, and the center side of the plate portion 29A having the slit 29C is surrounded by this annular thin wall portion 29D. A plurality of annular seal protrusions 29a are formed concentrically on the upper surface of the outer peripheral portion 29B, and an annular seal protrusion 29b is also formed on the lower surface.

9B is the flange 2a of the opening 2A and the plate 28 of the cap 28.
A and the opening 2A is sealed. 1st
In the figure, G indicates the sealing material 29 and the plate portion 2 of the cap 28.
This is a passage that connects the space defined by 8A to the outside of the cap.

により吸収され、スリット２９Ｃ側には及ばない。In this configuration, when the opening 2A of the cap 28 is attached by rotation, the outer periphery 29B of the sealing material 29 becomes larger as the cap rotation progresses and the pressing force acting on the outer periphery 29B of the sealing material 29 increases. 29B may twist due to the rotational force from the palm 128 side and the frictional force from the flange 2a side of the opening 2A, and this twist spreads to the plate portion 29A side, but the thin wall portion 29D is is also easy to deform, so
The diffused twist is absorbed by the deformation of the thin portion 29D and does not extend to the slit 29C side.
従って、本実施例によれば、キャップ２８の取付は時に

Even if the outer periphery is warped, the effect of the warp is absorbed by the deformation of the thin wall part, so the plate part will not be assembled to the reservoir body in a deformed position.
Reliability can be improved compared to the conventional method.
