載の摩擦ロツク装置。[Claims for Utility Model Registration] (1) A shaft member that is inserted between a movable member and a fixed member, one side of which is inserted into the movable member so that it can slide in the axial direction while being rotationally restrained. A friction lock device characterized in that the other side portion is press-fitted into the fixing member, and the frictional force generated between it and the fixing member can be varied depending on the length of the press-fit. (2) The friction lock device according to claim 1, wherein the shaft member is a solid shaft member such as a parallel pin or a tapered pin, or a shaft member that is flexible in the radial direction. (3) The friction lock device according to claim (1), wherein the shaft member has a rotation preventing process such as a knurling on the outer periphery of the insertion portion on the movable member side. (4) The friction lock device according to claim 1, wherein the insertion hole of the shaft member of the fixing member is a cylindrical hole, a stepped hole, or a tapered hole.
