Abstract
An orifice device is adapted to be disposed within a fluid chambers of a vibration absorption device. The fluid chamber is defined by at least a wall portion made of resilient material. The orifice device includes an orifice casing, a retaining cover and a membrane that is made of resilient material, such as rubber. The membrane is adapted to be clamped between the orifice casing and the retaining cover. A lock mechanism serves to lock the orifice casing and the retaining cover together when the orifice casing and the retaining cover rotate relative to each other about an axis while the orifice casing and the retaining cover are overlapped with each other.
