WIPO Patent Application WO/2005/100815
Kind Code:

Abstract:
A vibration isolation device allowing an increase in the durability of the fixing structure of a member such as an agitating plate to a first mounting device by securely fixing the member such as the agitating plate to the mounting end part of the first mounting device even if the first mounting device is formed of a brittle metal such as an aluminum die cast, comprising a first mounting metal bar (1), a second mounting metal (2), a vibration isolating base (3), a diaphragm (9), a partition body (12), an orifice (25), and the agitating plate (60). The mounting end part (65) of the first mounting metal bar (1) is passed through a mounting hole (70) in the agitating plate (60), and one plate face (72) of the agitating plate (60) is received by a receiving surface part (71). The projected portion (73) of the moving end part (65) is radially enlarged so that the cross sectional shape of the peripheral wall (74) of the mounting end part (65) at the projected portion (73) is formed in an arc shape and the projected end face portion (76) thereof on the peripheral wall (74) side is formed in a spherical shape.
