Title: FLUID PRESSURE CYLINDER
Abstract:
A hydraulic cylinder (100) is provided with a cylinder tube (10) and a cylinder bottom (20) which is provided at one end of the cylinder tube (10). The cylinder bottom (20) has: a flange (22) joined to the cylinder tube (10); a base (23) protruding from the flange (22) in the axial direction of the cylinder tube (10) and having a circular outer peripheral surface (23a); and a mounting section (24) extending from the base (23) in the axial direction of the cylinder tube (10) and mounted to another device. The mounting section (24) has: two flat surface sections (24a) parallelly extending from the base (23); and two curved surface sections (24b) extending from the base (23) and adjacent to the two flat surface sections (24a). The hydraulic cylinder (100) is characterized in that the curvature radius L4 of the curved surface sections (24b) is the same as the curvature radius L1 of the base (23).
