In the configuration of the present embodiment, when an excessive load is applied to the head support portion 200 from a source other than the moving mechanism 500 (when a load exceeding a predetermined load is applied), the interlocking member 400 rotates. A slip occurs between the head support section 200 and the body 510, and the posture of the head support section 200 changes.

As a result, in the present embodiment, load is less likely to be transmitted to the moving mechanism 500, and damage to the moving mechanism 500 is less likely to occur.
Here, if there is no place where slippage occurs, the load is likely to be transmitted from the head support section 200 to the moving mechanism 500, and the moving mechanism 500 is likely to be damaged.
In contrast, when slippage occurs as in the present embodiment, the load is less likely to be transmitted to the moving mechanism 500, and damage to the moving mechanism 500 is suppressed.

Further, the member to be detected 39 is provided with end projecting portions 39</b>B projecting in the thickness direction of the interlocking member 400 at both ends of the member to be detected 39 in the longitudinal direction.

In this embodiment, when the head support part 200 is at the center in the moving direction, the center protrusion 39A is detected by the first center sensor 31 and the second center sensor 32 .
The control device 80 determines that the head support portion 200 is positioned at the central portion when the central protrusion portion 39A is detected by the first central sensor 31 and the second central sensor 32 .

In addition, when the first end sensor 33 detects one end projection 39B (on the left side in the figure), the control device 80 determines that the head support 200 moves in the moving direction of the head support 200. It is judged to be located at one end.
Further, when the second end sensor 34 detects the other end projection 39B (on the right side in the drawing), the control device 80 determines that the head support 200 is positioned in the moving direction of the head support 200. It is determined that it is located at the other end.

In the present embodiment, the head support section 200 moves and the posture of the head support section 200 changes according to instructions from the doctor.
Specifically, when the doctor changes the posture of the head support section 200, the doctor operates an operation receiving section (not shown) such as a foot switch.
As a result, a signal is output from the operation receiving unit to the control device 80 , and the control device 80 rotates the motor 70 accordingly.

As a result, for example, the headrest 2d rotates (moves) in the direction indicated by the arrow 1A in FIG. This causes the patient to turn to one side.
Also, for example, the headrest 2d rotates (moves) in the direction indicated by the arrow 1B in FIG. This causes the patient to turn to the other side.
