Document Type and Number:
WIPO Patent Application WO/1993/001425
Kind Code:
A1
Abstract:
A damper mechanism provided in a cylinder (1) thereof with a movable shaft (2), a check valve portion (9d), a partition portion (11c), an oil flow path (16) and the like. Working oil (10) is filled up in respective volume-variable chambers (31 and 32) in the cylinder (1), which are defined by these check valve portion (9d) and partition portion (11c), so that a cusioning action takes place for controlling the movement of the movable shaft (2) when the movable shaft (2) is rotated in a predetermined direction. The damper mechanism, having the above-mentioned arrangement, achieves the aforesaid action, so that stability for a long period of time, durability and economies of construction can be secured.
