Title (EN) VIBRATION ISOLATION DEVICE
(FR) DISPOSITIF D'ISOLATION DE VIBRATIONS
(JA) 防振装置
Abstract:
(EN) The present invention relates to a vibration isolation device (1, 2) which is provided with an external member (11, 21) attached to either one of a vibration generation part and a vibration receiving part, a tubular member (40) which is attached to the other one of the vibration generation part and the vibration receiving part, and an elastic body (30) which connects the external member (11, 21) and the tubular member (40), wherein: the external member (11, 21) is provided with a frame-like member (11, 21) formed in a top-view rectangular shape; the elastic body (30) is formed in a rectangular parallelepiped having a top-view rectangular shape; in the elastic body (30), a long-side portion (32a) constituting a long side of the top-view rectangular shape is adhered to an inner peripheral surface of a long side portion (12a, 12b) of the frame-like member (11, 21); and a short-side portion (32b) constituting a short side of the top-view rectangular shape is, in a non-adhered state, in contact with the external member (11, 21) in a long-side direction (X) in which the long-side portion (12a, 12b) extends in top view.
(FR) La présente invention concerne un dispositif (1, 2) d'isolation contre les vibrations qui comporte un élément (11, 21) externe fixé soit à une partie de génération de vibrations soit à une partie de réception de vibrations, un élément tubulaire (40) qui est fixé à l'autre élément parmi la partie de génération de vibrations et la partie de réception de vibrations, et un corps élastique (30) qui relie l'élément (11, 21) externe et l'élément tubulaire (40), l'élément (11, 21) externe étant pourvu d'un élément (11,21) de type châssis formé de sorte à avoir une forme rectangulaire en vue de dessus ; le corps élastique (30) étant formé de sorte à avoir une forme de parallélépipède rectangle ayant une forme rectangulaire en vue de dessus ; dans le corps élastique (30), une partie (32a) côté long constituant un côté long de la forme rectangulaire en vue de dessus est collée à une surface périphérique interne d'une partie (12a, 12b) côté long de l'élément (11, 21) de type châssis ; et une partie (32b) côté court constituant un côté court de la forme rectangulaire en vue de dessus est, dans un état non collé, en contact avec l'élément (11, 21) externe dans une direction grand côté (X) dans laquelle la partie (12a, 12b) côté long s'étend en vue de dessus.
(JA) 本発明は、振動発生部および振動受部の一方に取付られる外側部材(11、21)と、振動発生部および振動受部の他方に取付られる筒状部材(40)と、外側部材(11、21)と筒状部材(40)とを連結した弾性体(30)と、を備え、外側部材(11、21)は、上面視長方形状を呈する枠状部材(11、21)を備えるとともに、弾性体(30)は、上面視長方形状を呈する直方体状に形成され、弾性体(30)のうち、上面視長方形状の長辺をなす長辺部分(32a)は、枠状部材(11、21)の長辺部分(12a、12b)の内周面に接着され、かつ上面視長方形状の短辺をなす短辺部分(32b)は、外側部材(11、21)に上面視で長辺部分(12a、12b)が延びる長辺方向(X)に、非接着状態で当接している防振装置(1、2)である。
