Abstract
A seal member includes a base portion held by a cylinder, the base portion being configured such that a rod is inserted through the base portion, and a lip portion provided on the base portion, the lip portion being brought into sliding contact with an outer circumference of the rod, wherein the lip portion is formed of an elastic body containing fibers oriented in the axial direction of the rod.
Claims5
A seal member provided in a fluid pressure apparatus including a cylinder and a rod inserted into the cylinder so as to be movable in an axial direction of the cylinder, the seal member for closing a gap between the cylinder and the rod, the seal member comprising:
- a base portion held by the cylinder, the base portion being configured such that the rod is inserted through the base portion;
- and
- a lip portion provided on the base portion and projecting radially inward, the lip portion being in sliding contact with an outer circumference of the rod when the rod is moved in the axial direction, wherein
- the lip portion is formed of an elastic body containing fibers oriented in the axial direction and
- a modulus of elasticity of the lip portion in both a radial direction and a circumferential direction of the cylinder is lower than a modulus of elasticity of the lip portion in the axial direction.
