摘要： A main shaft drive includes a supply groove that opens to a friction surface, that extends so as to surround a main shaft within a contact range where the friction surface and a pressing surface oppose each other, and that includes an intersecting groove and a discharge opening. The intersecting groove extends in a direction of intersection with a circumference in which a rotational center of the main shaft is a center. The discharge opening is connected to a location that is outside the contact range. By opening a nozzle hole, used for supplying lubricant, towards the supply groove, as the main shaft rotates, four intersecting grooves move relative to the contact range, so that the lubricant is supplied to the four moved intersecting grooves. Therefore, the lubricant easily reaches a location within the contact range where the friction surface and the pressing surface oppose each other.

摘要翻译： 主轴驱动器包括供给槽，该供给槽向摩擦面开放，该供给槽在摩擦面和按压面相对的接触范围内包围主轴，并且包括交叉槽和排出口 。 交叉槽沿与主轴的旋转中心为中心的圆周交叉的方向延伸。 排出口连接到接触范围以外的位置。 当主轴旋转时，通过打开用于向供给槽供给润滑剂的喷嘴孔，四个相交槽相对于接触范围移动，从而将润滑剂供应到四个移动的交叉槽。 因此，润滑剂容易到达摩擦面和按压面相对的接触范围内的位置。

摘要： A slide disk that is displaceable when the slide disk is bent toward a base section of a frame is provided at a main shaft, and a friction surface that can contact a pressing portion of the slide disk is provided at the base section. The pressing portion of the slide disk normally presses the friction surface to cause the pressing portion of the slide disk to normally press the friction surface, and hence a pressing force for applying to the main shaft a rotational resistance that permits rotation of the main shaft normally acts on the main shaft. Accordingly, even if the position of the center of gravity of a member to be rotated is deviated from a rotation axis of the main shaft, the rotational resistance can be applied to the main shaft.

摘要翻译： 在主轴上设置有滑动盘向框架的基部弯曲时可移动的滑动盘，并且在基部设置能够接触滑动盘的按压部的摩擦面。 滑动盘的按压部分通常按压摩擦面，使得滑动盘的按压部分正常地按压摩擦面，因此用于向主轴施加允许主轴正转的旋转阻力的按压力 作用在主轴上。 因此，即使要旋转的构件的重心位置偏离主轴的旋转轴，也可以对主轴施加旋转阻力。
