Abstract
A fluid pressure cylinder including a first damper and a second damper provided respectively on a head cover and a rod cover, which are disposed on both ends of the fluid pressure cylinder so as to face toward a piston. The first damper and the second damper are formed from an elastic material, and are made up from a main body portion against which the piston abuts, and a plurality of legs that project from the main body portion and which are gripped between the head cover and the rod cover and an inner wall surface of the cylinder tube.
Claims12
A fluid pressure cylinder comprising:
- a cylinder body having a cylinder chamber defined therein;
- a piston that is disposed displaceably along an axial direction inside the cylinder chamber;
- a cover member accommodated inside the cylinder chamber that blocks and seals the cylinder chamber, a side of the cover member that faces toward the piston including a recess that extends across a width of the cover member from an outer edge of the cover member to an opposing outer edge of the cover member;
- and
- a damper disposed on the cover member, which absorbs shocks when the piston abuts against the cover member,
- the damper being formed from:
- a main body portion that faces toward the piston and is disposed in the recess;
- and
- a retaining member that extends perpendicularly to the main body portion and is engaged with a side surface of the cover member,
- wherein the retaining member is gripped between the side surface of the cover member and an inner wall surface of the cylinder body.
