Claims

[Scope of Claim for Utility Model Registration] 1. A fluid pressure device that is equipped with a connection recess in which a connection port for an accessory device is opened at approximately the center of the bottom surface, and a device that fits into the connection recess of the fluid pressure device. a first male fitting part is formed on one of the inner circumferential surface side of the recessed part or the outer circumferential surface side of the protruding part; a passage portion through which the first male fitting portion passes when the protrusion and the recess are attached and detached; and a first male fitting portion passing through the passage portion forming a circle on the outer circumferential surface of the protrusion. a first female fitting part that is rotatably fitted along the circumferential direction, and the fluid pressure opposite to one end surface of the accessory device in the axial direction of the protruding part or this one end surface; A second male fitting part is formed on one of the facing surfaces of the device, and the second male fitting part is fitted on the other side by rotation of the first male fitting part. A connection structure for an accessory device of a fluid pressure device, characterized in that a second female fitting portion is formed therein. 2. The connection structure for an accessory device of a fluid pressure device according to claim 1, wherein the entire protruding portion is fitted into the recessed portion to connect the accessory device to the fluid pressure device.
