Claims

[Scope of utility model registration request]

(1) An oil reservoir for a hydraulic vibration isolator, comprising a cup-shaped main body having a male thread on the upper external thorax, and a lid having a female thread on the inner periphery that is screwed into the female thread, the lid being located below the female thread. an annular skirt portion that hangs down, and when the lid is attached to the main body, a space is defined outside the main body and above the female screw, and the space is communicated with the inside of the main body. An oil reservoir for a hydraulic vibration isolator, characterized in that an air bleed passage is formed.

(2) Hydraulic vibration isolation according to claim 1 of the utility model registration claim, characterized in that the air bleed passage is an air bleed hole penetrated in a portion above the male thread of the cup-shaped main body. Dexterous oil reservoir.

(3) The air bleed passage is defined by an air bleed notch provided at the upper end of the cup-shaped body or at the abutting end of the annular protrusion provided on the downwardly facing bottom surface of the lid to abut the upper body. An oil reservoir for a hydraulic vibration isolator according to claim 1, characterized in that:
