Title:
FLUID PRESSURE CYLINDER
Document Type and Number:
WIPO Patent Application WO/2011/024537
Kind Code:
A1
Abstract:
In a fluid pressure cylinder (1), a piston (40) abuts a cylinder head (30), with the fluid pressure cylinder (1) in the maximum extended position. The cylinder head (30) is fixed to a cylinder tube (10) with a plurality of head bolts (12). The cylinder head (30) is provided with a tubing mounting seat (36). Head bolts (12) are disposed in first regions (A) which are located away from the tubing mounting seat (36). Areas where the piston (40) and the cylinder head (30) are not in contact with each other are formed in second regions (B) that are regions other than the first regions (A), thereby achieving a situation where the tensile loads applied to the head bolts (12) at both ends of the first regions (A), with the fluid pressure cylinder (1) in the maximum extended position, can be restrained to a level equivalent to those applied to the other head bolts (12).
