る。The pin body 97, which is inserted from the side of the clutch body 96, has its tip inserted into the engagement hole 98 of the pivot 40, and the clutch body 96 and the pivot 40
And rotate together. The rotating body 68 is formed with a recess 101 for accommodating the engagement / disengagement body 100 which is biased outward by a spring 99, and the clutch body 96 is formed with a plurality of engagement portions 102 for engagement / disengagement of the engagement / disengagement 100. . When the engagement / disengagement body 100 engages with the engaging portion 102 of the clutch body 96, the rotating body 68 and the clutch body 96 rotate together, and rotate together with the pivot 40. Since the pin body 97 is located at the back of the base 3, it is difficult to screw it in with a jig. Therefore, the pin body 97 is simply inserted, and the retaining portion 103 is formed on the rotating body 68 as a retaining means. There is. When the swinging electric motor 2 rotates, the cam body 62 rotates, and the rotation of the pivotal support portion of the swinging link 65 moves toward and away from the rotating body 68. Therefore, the swinging link 65 rotates. The rotating body 68 is reciprocally rotated by a pushing force and a pulling force on the outer peripheral portion of the body 68. When the rotating body 68 reciprocally rotates, the pivot 40 is reciprocally rotated via the clutch body 96, and the reciprocating rotation of the rotation support base 4 causes the fan main body 6 to swing right and left. By engaging the fan main body 6 with a force for forcibly swinging to the left and right, the engaging portion 102 of the engaging and disengaging body 100
The center of the left and right swing can be changed by changing the position of engagement with.

を被嵌している。The output shaft 60 and the pivot shaft 40 of the swing motor 2 are a single mounting plate.
At 59, the distance becomes stable, and the pivot 40 is attached to the shaft support hole 41.
Since it is pivotally supported at the lower part, twisting of the pivot 40 is prevented, and stable swinging is performed. The outer circumference of the cylinder shaft 69 of the rotating body 68 hanging from the mounting plate 59 is the brake spring 104.
Is inlaid.

体68と枢軸40とをピン体にて一体化すればよい。In this structure, the rotating body 68 is pivotally supported on the mounting plate 59 by the cylinder shaft 69, but the rotating body 68 is pivotally supported on the pivot shaft 40 and the pivot shaft 40 is directly mounted on the mounting plate 59.
The bearing holes 61 of 59 may be pivotally supported. Further, when it is not necessary to change the swing center, the clutch body 96 is not necessary, and the rotating body 68 and the pivot 40 may be integrated by a pin body.
