摘要： A rotational resistance applying device in which a hollow roller is provided between a first surface of a clamp piston (pressing member) and a second surface of a sliding disc (a press member), and in which a pressing force applied to the clamp piston acts upon the sliding disc through the hollow roller that press-contacts the first and second surfaces by displacement of the clamp piston. By this, rolling resistance of the hollow roller resiliently deformed by the pressing force causes a rotational resistance to be applied to a main shaft within a range allowing rotation. This makes it possible to prevent pulsation from being generated in the rotation of the main shaft. In addition, even if the pressing force is applied to the clamp piston, the hollow roller rolls, so that wear of the clamp piston and wear of the sliding disc can be restricted.

摘要： In a spindle head for a machine tool in which a spindle (10) to which a tool is mounted is rotated around an axial line of a support shaft (58, 59), two rotating members (9, 58) that form a rotation transmission mechanism for rotating the spindle (10) and that transmit drive force of the rotation driving device (56) are fastened to each other at respective connection sections thereof by a bolt group (301) and are connected to each other so as to be prevented from rotating relative to each other by friction force resulting from the fastening. Rotation prevention torque based on the friction force is a value greater than torque applied to the connection sections during processing and smaller than torque applied to the connection sections when external force that causes the spindle (10) to deform beyond a permissible range is applied to the spindle (10). Therefore, even if the tool or the spindle (10) collides with, for example, a processing tool, the spindle (10) does not become deformed beyond the permissible range.
