UPPER MOUNT

An upper mount (2) with which a vehicle height can be increased and reduced at any time using a vehicle-mounted existing fluid device (hydraulic device, for example) without using a dedicated fluid pressure mechanism such as a pneumatic device and without affecting suspension performance at all. The upper mount (2) is composed of a body-side member (4) fixed to a body (8) and a suspension-side member (6) fixed to (an upper end portion (38) of) a suspension. [0002] The suspension-side member (6) is slidably installed to the body-side member (4) with a sealed space (28) formed between both members. [0003] Fluid passage holes (oil passage holes) (18, 18) are made in the body-side member (4) from the outside. When fluid is supplied to the sealed space (28), the spacing between the suspension-side member (6) and the body-side member (4) is widened and a vehicle height can be increased.
