A strut mount includes: an inner member coupled to a suspension; an outer bracket having an outer cylinder portion housing the inner member, and a flange portion protruding radially outward from the outer cylinder portion and coupled to a vehicle body; an elastic member interposed between the inner member and the outer cylinder portion; and a seal member interposed between the flange portion and the vehicle body. The seal member includes an annular portion located between the flange portion and the vehicle body, and a first downward extending portion extending downward from an outer peripheral portion of the annular portion toward the opposite side from the vehicle body. The flange portion includes a placement surface portion which faces toward the vehicle body and on which the annular portion is placed, and a first sidewall portion extending from an outer peripheral portion of the placement surface portion to the opposite side from the vehicle body. A first engaging portion of the first downward extending portion and a first engaged portion of the first sidewall portion are engaged with each other to reduce axial movement of the annular portion placed on the placement surface portion.

Suspension mount

A liquid-filled vibration isolator has a first orifice channel providing communication between a pressure receiving chamber and a balancing chamber. One of the pressure receiving chamber and the balancing chamber is communicated via a second orifice channel with an intermediate liquid chamber. The second orifice channel has a shorter distance or a larger cross-sectional area than the first orifice channel. An elastic film member, such as a membrane, separates the intermediate liquid chamber and the other of the pressure receiving chamber and the balancing chamber from each other. A communicating hole of a predetermined size is formed in the elastic film member. An imaginary orifice channel combined from the two orifice channels provides a high damping effect on input vibration of relatively low frequency. As the vibration frequency increases, a gradual transition is made to the damping characteristic of the second orifice channel only.
