Abstract: A tilt angle adjuster includes a base plate attached to a Z slider; a hanging plate attached to a measuring device main body; a thin coupling plate supporting the hanging plate such that the hanging plate is suspended on a first surface side of the base plate; biasers biasing the hanging plate so as to impart a rotational force in a first direction to the hanging plate; and a micrometer head provided so as to push the hanging plate one of directly and indirectly toward a second direction opposite the direction of the rotational force imparted by the biasers.

Abstract: A traction nut has twist rollers pivotally supported so as to be rotatable in a state of defining an inclination angle with respect to an axis of a drive shaft, the inclination angle being equivalent to a lead angle; an open/close lever provided to switch between a friction-contact state and a disengaged state of the traction nut relative to the drive shaft; and a spring generating a biasing force such that the traction nut is brought into friction-contact with the drive shaft. In response to user operation, the open/close lever puts the traction nut in the disengaged state against the biasing force of the spring. When the user releases the open/close lever, the traction nut returns to the friction-contact state due to the biasing force of the spring.

Abstract translation: 牵引螺母具有可旋转地支撑的扭转辊，以便能够相对于驱动轴的轴线限定倾斜角度的状态旋转，该倾斜角度等于导程角; 一个打开/关闭杆，用于在摩擦接触状态和牵引螺母相对于驱动轴的脱离状态之间切换; 以及产生偏压力的弹簧，使得牵引螺母与驱动轴摩擦接触。 响应于用户操作，打开/关闭杆克服弹簧的偏置力使牵引螺母处于分离状态。 当用户释放打开/关闭杆时，牵引螺母由于弹簧的偏置力而返回到摩擦接触状态。
