とで円形部66は偏心回転する。A cam body 62 is attached to the output shaft 60 of the swinging electric motor 2, and a shaft 63 is formed on the upper surface of the cam body 62 which is an extension of the output shaft 60.
Is rotatably supported by a bearing portion 64 formed on the inner surface of the base 3. One end of a swing link 65 is fitted and supported on the lower circular portion 66 of the cam body 62. A collar is formed on the circular portion 66, and the swing link 65 is sandwiched between the collar and the mounting plate 59 so as to be rotatably supported. The center of the circular portion 66 is formed so as to be offset from the center of rotation of the output shaft 60, so that the circular portion 66 rotates eccentrically.

付板59の下面に筒軸69と共に突出する。In the bearing hole 61 of the mounting plate 59, a cylindrical shaft 69 of a rotating body 68 having a projection 67 for pivotally supporting the other end of the swing link 65 formed on the outer peripheral portion is pivotally supported. A clutch body 96 having an insertion hole 95 for the pivot 40 is fitted on the rotary body 68. As shown in FIG. 1, the pivot 40 is inserted into the through hole 95 of the clutch body 96 and the tubular shaft 69 of the rotary body 68, and projects together with the tubular shaft 69 on the lower surface of the mounting plate 59.

体68に抜け止め部103を形成している。The tip of the pin body 97 inserted from the side of the clutch body 96 is inserted into the engagement hole 98 of the pivot 40, and the clutch body 96 and the pivot 40 rotate together. The rotating body 68 is formed with a recess 101 for accommodating the engagement / disengagement body 100 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 integrally,
It will rotate together with the pivot 40. Pin body 97 is base 3
Since it is located at the back, it is difficult to screw it in with a jig. Therefore, the retainer portion 103 is formed in the rotary body 68 as a retainer only by being inserted.

変更できる。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 forcibly applying a force to the fan main body 6 to swing to the left and right, the engagement position of the engaging and disengaging body 100 with the engaging portion 102 can be changed, and the center of the left and right swing can be changed.

嵌している。The output shaft 60 and the pivot shaft 40 of the swinging electric motor 2 have a single mounting plate 59.
At that time, the distance between the shaft 40 is stabilized, and the shaft 40 is pivotally supported by the shaft support hole 41 and the lower part, so that the torsion of the shaft 40 is prevented,
Have a stable swing. A brake spring 104 is fitted on the outer periphery of the cylindrical shaft 69 of the rotating body 68 that hangs from the mounting plate 59.
