(JA) マスタシリンダ
Abstract:
(EN) A seal member (45) has: a base (101) which is capable of coming into contact with the cylinder opening-side circumferential wall (89) of a circumferential groove (32); an inner circumferential lip (102) extending toward the cylinder bottom side from the base (101) and in sliding contact with the outer periphery of a piston (18); and an outer circumferential lip (103) extending toward the cylinder bottom side from the base (101) and in contact with the groove bottom (88) of the circumferential groove (32). The circumferential groove (32) has a sloped section (91) which slopes and extends from the cylinder bottom-side end of the groove bottom (88) so that the sloped section (91) comes closer to the cylinder bottom side as the sloped section (91) extends radially inward. A cylinder body (15) has formed therein a groove (51) which is open to the sloped section (91) and which extends from the circumferential groove (32) toward the cylinder bottom side.
(FR) Un élément d'étanchéité (45) comprend : une base (101) qui peut entrer en contact avec la paroi circonférentielle côté ouverture de cylindre (89) d'une rainure circonférentielle (32) ; une lèvre circonférentielle interne (102) s'étendant en direction du côté fond de cylindre à partir de la base (101) et en contact coulissant avec la périphérie externe d'un piston (18) ; et une lèvre circonférentielle externe (103) s'étendant en direction du côté fond de cylindre à partir de la base (101) et en contact avec le fond de rainure (88) de la rainure circonférentielle (32). La rainure circonférentielle (32) comprend une section inclinée (91) qui est inclinée et s'étend à partir de l'extrémité côté fond de cylindre du fond de rainure (88) de sorte que la section inclinée (91) se rapproche du côté fond de cylindre lorsque la section inclinée (91) s'étend radialement vers l'intérieur. Un corps de cylindre (15) comprend, formée en son sein, une rainure (51) qui est ouverte sur la section inclinée (91) et qui s'étend à partir de la rainure circonférentielle (32) en direction du côté fond de cylindre.
(JA) シール部材(45)は、周溝(32)におけるシリンダ開口側の周壁(89)に当接可能なベース部(101)と、ベース部(101)からシリンダ底側に向けて延出してピストン(18)の外周に摺接する内周リップ部(102)と、ベース部(101)からシリンダ底側に向けて延出して周溝(32)の溝底(88)に当接する外周リップ部(103)とを有する。周溝(32)は、溝底(88)のシリンダ底側の端部から径方向内方に向けて径方向内側ほどシリンダ底側に位置するように傾斜して延出する傾斜部(91)を有する。シリンダ本体(15)には、傾斜部(91)に開口して周溝(32)からシリンダ底側に向けて延びる溝(51)が形成されている。
