摘要： This invention provides a switching type liquid-in vibration isolating device capable of opening/closing an orifice by changing over between the atmospheric and negative pressure in a switching chamber corresponding to shake and idle vibration, respectively. In order to prevent a pipe, for introducing the atmospheric and negative pressure in the switching chamber, from disconnecting, a first and a second fitting 1, 2 are connected by a vibration isolating substrate 3, a partition member 4, a first and a second diaphragm 5, 6 are disposed within a hollow space thereof, a main liquid chamber 7 and a sub-liquid chamber 8 are interconnected by two inside and outside orifices 12, 13, a equilibrium chamber 9 is formed between the first and second diaphragm 5, 6, a switching chamber 10 is formed between the second diaphragm 6 and the second fitting 2, the center portion of the bottom wall 22 of the second fitting 2 is depressed toward the switching chamber 10, a pipe 11 is pierced into the top 25a of the depressed portion 25 and received in the depressed portion 25, and a plurality of convex portions 29 for interference prevention are outwardly projectively provided on the bottom wall 22 around the depressed portion 25.

摘要： An engine mount includes an inner member and an outer cylinder having a circumferential position around a central axis of the engine mount, the circumferential position being changeable relative to the inner member. A bracket fixed to the inner member supports an engine on the engine mount, the bracket having a circumferential position around the central axis of the engine mount which is changeable relative to the outer cylinder. A stopper of an elastic material is provided on one of the outer cylinder and the inner member, the stopper contacting the other of the outer cylinder and the inner member when a change in length of one of the outer cylinder and the inner member relative to the other exceeds a reference level. An interconnecting member of an elastic material exerts a pressing force on the outer cylinder and the inner member such that the other of the outer cylinder and the inner member is contacted by the stopper to prevent the change in length of one of the outer cylinder and the inner member from further increasing from the reference level. A reference position indicating unit indicates whether the circumferential positions of the outer cylinder and the bracket relative to each other around the central axis of the engine mount are reference positions.
