    • A contact block (31) is provided with a flat face portion (311A) parallel with the axis of a spindle (12) and a conical face portion (311B) that comes closer to the flat face portion (311A) along the axial direction of the spindle (12) in the direction of going away from the spindle (12). Even in the case of a shape formed by integrating a step and a gap inseparably, since the flat face portion (311A) is parallel with the axis of the spindle (12), it is possible to insert the contact block (31) into the gap while the axis of the spindle (12) is kept perpendicular to the direction of the gap, hence it is possible to measure the gap W accordingly
    • 接触块(31)设置有平行于主轴(12)的轴线的平面部分(311A)和沿着平面部分(311A)更靠近平面部分(311A)的锥形面部分(311B) 主轴(12)的轴向方向远离主轴(12)。 即使在通过使步进和间隙不可分离地形成的形状的情况下,由于平面部(311A)与心轴(12)的轴线平行,因此能够将接触块(31)插入 当主轴(12)的轴线保持垂直于间隙的方向时的间隙,因此可以相应地测量间隙W
