In addition, 11 is a first arm, 12 is a second arm, 13 is a third arm, 14 is a surgical light, 15 is a first joint, 16 is a second joint, and 17 is a third joint, which are not used during dental treatment. The shadow lamp 14 is set at the solid line position shown in the figure to illuminate the patient's oral cavity to perform necessary treatment, and when not in use, it is kept at the dotted line position. Conventionally, the operation of moving the surgical light 14 was done manually, but automation has recently progressed, and for example, the surgical light is moved in conjunction with the raising of the treatment chair. At that time, the first joint 15
If the surgical light 14 is rotated around , the surgical light 14 will move within the range of arrow A, requiring a wide movement space.

is a fixed main pillar, 19 is a first rotating main pillar (corresponding to the first joint 15 in FIG. 1), 20 is a second rotating main pillar,
These first rotating main pillar 19 and second rotating main pillar 20
are arranged to be rotatable concentrically, and the first arm 11 extends horizontally from the upper part of the second rotating main column 20. 21 is a motor, 22 is an electromagnetic clutch,
23 and 24 are gears connected to the rotating shaft of the motor 21 via the electromagnetic clutch 22, 25 is a gear integral with the first rotating main column 19, and 26 is a gear connected to the second rotating main column 20. Gear 23 is an integrated gear.
and 25 and gears 24 and 26 are in mesh with each other, so that when the motor 21 is rotated, the first rotating main column 19 rotates faster than the second rotating main column. Note that the electromagnetic clutch 22 is normally disengaged, and the first arm 11 can be freely rotated manually. 28 is a chain belt, and the chain belt 28 is rotatably provided at the upper end of the first rotating main column 19 (that is, corresponding to the first joint 15 in FIG. 1) and at the tip of the horizontal arm 11. When the first joint 15 rotates in the direction of arrow B (or B') in FIG. ,
The second joint 16 is adapted to rotate in the direction of arrow C (or C'). Therefore, if the motor 21 is driven when the surgical light 14 is at the solid line position in FIG. 12) rotates in the direction of arrow C, and the second and third arms 12,
13 returns to the dotted line position shown in the drawing while maintaining a state substantially parallel to the axis XX of the treatment chair, that is, without going out of the range of the treatment chair. On the contrary, shadowless light 14
To move from the dotted line position to the solid line position, the motor 21 is rotated in the opposite direction to the first joint 1.
5 in the direction of arrow B' and the second joint 16 in the direction of arrow C'.

効果以上の説明から明らかなように、本考案によれ
