Abstract

PURPOSE:To obtain anti-vibration and damping effects when either high frequency deviation or low frequency deviation is inputted, by providing a fluid pressure type damper mechanism with a fluid pressure adjusting means so that an initial inner pressure in a working fluid can be adjusted to a predetermined value at the outside of the mechanism. CONSTITUTION:A cylindrical body 10 is deformed vertically and inwardly in accordance with fluctuations in weight of an engine and attachments mounted thereto, an initial inner pressure in a working fluid rising up. Then, when the initial inner pressure becomes over a predetermined value, a ball valve 51 of a fluid pressure adjusting means 50 is opened and then the working fluid in a fluid chamber is discharged through discharge holes 40a and 54a, so that irrespective of fluctuations in engine weight due to mounted attachments and of tolerence in manufacture of a composite engine mount M1, an initial inner pressure is maintained at a predetermined value. Accordingly, if an adjusting nut 54 is tightened to block a moving down of the ball valve 51, the change in characteristic of the mount M1 can be preventd, causing an expected function to be shown.
