ダンパー
Document Type and Number:
Japanese Patent JP6576321
Kind Code:
B2
Abstract:
A damper includes a piston provided with a rod, and a housing storing the piston, and generates a braking force by an operation of the piston. The piston includes a seal member relative to an inner wall of the housing; and a slider contacting the inner wall of the housing with a predetermined frictional force. When the braking force is generated, the slider presses against the seal member, and a portion contacting the inner wall of the housing in the seal member deforms toward an outside of the housing. At an inner side of the portion contacting the inner wall of the housing in the seal member, a deformation control portion is provided, which suppresses the seal member from deforming toward an inside of the housing.
