Claims

[Scope of Claim for Utility Model Registration] 1. In a clamp attachment that is attached to a forklift truck, etc. and configured so that a pair of clamp arms slide in the left and right direction to clamp cargo from both sides, the thrust of the clamp cylinder is applied to the clamp arms. In order to provide the clamp cylinder with a self-aligning function, the spherical nut that is threaded onto the tip of the piston rod of the clamp cylinder is always urged in the direction away from the clamp cylinder along the axial direction. A fixing device for a clamp attachment of a forklift truck or a cylinder self-aligning nut, characterized in that an attachment member is provided concentrically with a piston rod. 2. The forklift truck according to claim 1, wherein the tightening member is a lock plug screwed into the female threaded portion of the spherical nut so as to come into contact with the tip of the piston rod. Fixing device for cylinder self-aligning nuts in clamp attachments such as. 3. Registration of a utility model characterized in that the tightening member is a nut that is located closer to the clamp cylinder than the spherical nut and is screwed into the male threaded portion at the tip of the piston rod with one end of the tightening member in contact with the spherical nut. A fixing device for a cylinder self-aligning nut in a clamp attachment for a forklift truck or the like according to claim 1.
