Title:
FRICTION DAMPER
Document Type and Number:
WIPO Patent Application WO/2018/159296
Kind Code:
A1
Abstract:
Provided is a friction damper capable of suitably suppressing entry of foreign matter into a friction surface. A friction damper (1) is provided with a cylinder (10), a rod (20), a friction member (30), an elastic member (40), and a seal member (50). The cylinder (10) is formed like a tube. The rod (20) is capable of freely reciprocating in an axial direction and is partially housed in the cylinder (10). The friction member (30) is arranged inside the cylinder (10) to generate a damping force based on a frictional force generated between the friction member (30) and an outer circumferential surface (20C) of the rod (20) as a result of relative movement between the cylinder (10) and the rod (20). The elastic member (40) applies an elastic force in a direction in which the length of projection of the rod (20) on one end (20A) side from the cylinder (10) increases. The elastic force of the elastic member (40) is applied to the seal member (50). The seal member (50) is held by the elastic member (40) to seal a clearance (CP) through which the outside and the inside of the cylinder (10) communicate with each other.
