Title (EN) GASKET
(FR) JOINT D'ÉTANCHÉITÉ
(JA) ガスケット
Abstract:
(EN) The present invention addresses the problem of providing a gasket configured so that, during the mounting of the gasket to a counterpart member, the gasket can be self-retained without requiring a catch formed on the gasket body to be engaged with the counterpart member and will be unlikely to damage a counterpart wall surface. In order to solve this problem, the gasket is configured so that at least two catches 15 coming in contact with sidewall surfaces adjacent to a counterpart seal surface will be formed in a protruding manner on the gasket body 11 comprising a metallic base plate, the catches 15 respectively having curved sections 152 formed at the front ends of the catches 15, which come in contact with the sidewall surfaces, at least one of the catches 15 being formed bent toward the inner side of the gasket body 11 so that the angle formed between the gasket body 11 and the at least one of the catches 15 will be an acute angle, the spring force of the at least one of the catches 15, which is formed bent to the acute angle, pressing the bent section 152 against a sidewall surface to cause the gasket body 11 to be self-retained on the counterpart seal surface.
(FR) La présente invention vise à procurer un joint d'étanchéité conçu de telle sorte que, pendant le montage du joint d'étanchéité sur un élément en correspondance, le joint d'étanchéité peut être auto-maintenu sans nécessiter qu'un loquet formé sur le corps de joint d'étanchéité vienne en prise avec l'élément en correspondance, et est peu susceptible d'endommager une surface de paroi en correspondance. A cet effet, l'invention porte sur un joint d'étanchéité, lequel joint est conçu de telle sorte qu'au moins deux loquets (15) venant en contact avec des surfaces de paroi latérale adjacentes à une surface d'étanchéité en correspondance seront formés de manière saillante sur le corps de joint d'étanchéité (11) comprenant une plaque de base métallique, les loquets (15) comportant respectivement des sections incurvées (152) formées aux extrémités avant des loquets (15), qui viennent en contact avec les surfaces de paroi latérale, au moins l'un des loquets (15) étant formé de façon incurvée vers le côté interne du corps de joint d'étanchéité (11), de telle sorte que l'angle formé entre le corps de joint d'étanchéité (11) et au moins l'un des loquets (15) sera un angle aigu, la force de ressort du ou des loquet(s) (15), de forme incurvée par rapport à l'angle aigu, s'appuyant contre la section incurvée (152) contre une surface de paroi latérale pour amener le corps de joint d'étanchéité (11) à être auto-maintenu sur la surface d'étanchéité en correspondance.
(JA) 本発明は、相手部材への組付け時に、ガスケット本体に形成した係止爪部を相手部材に引っ掛ける必要がなく自己保持できるようにすると共に、相手壁面を傷付けるおそれもないガスケットを提供することを課題とし、該課題は、金属基板からなるガスケット本体11に、相手シール面に隣接する側壁面に当接する少なくとも2つの係止爪部15が突出形成され、係止爪部15は、側壁面と当接する係止爪部15の先端部に湾曲部152がそれぞれ設けられていると共に、少なくとも1つの係止爪部15は、ガスケット本体11とのなす角度が鋭角になるように該ガスケット本体11の内側に向けて折り曲げ形成されており、該鋭角に折り曲げ形成された係止爪部15のばね力で湾曲部152を側壁面に押圧し、ガスケット本体11を相手シール面に自己保持することにより解決される。
