PURPOSE:To reduce a clamp mechanism in size by engaging a male screw with a female screw formed on the side portion of a bearing body, and pressing a slide member to the sliding surface of a raceway table. CONSTITUTION:A bearing body 10 is substantially rectangular, and a substantially trapezoidal internal cavity is formed inside of the bearing body. A horizontal slide member 29 is fixed to the top wall 11 of the internal cavity. Side slide members 39, 40 are fixed to the side portions 36, 37 of the bearing body 10. A female screw 47 is formed on the side portion 37 of the bearing body 10, and a male screw 48 with a handle is engaged with the female screw 47. Therefore, the side sliding member 40 is pressed to the sliding surface of a raceway table 67 by fastening the clamping female screw 48, so that the bearing body 10 is clamped by the raceway table 67. |
