Claims

[Scope of utility model registration request]

A first propeller fan having an annular body on its outer periphery with a concave groove formed thereon, and three or more rotating wheels arranged at intervals from each other are brought into contact with the concave grooves on the outer circumferential surface of the annular body. A support that is rotatably supported, one of the three or more rotating wheels is a driving rotating wheel driven by a motor, and the remaining rotating wheels are freely rotated as the first propeller fan rotates. a rotary wheel, adjacent to the first propeller fan,
A second propeller huan having the same shape as the first propeller huan is fitted with three or more supporting rotary wheels spaced apart from each other in a concave groove on the outer circumferential surface of the annular body of the second propeller huan. Supported by abutting, near both the first and second propeller fans,
A rotating transmission wheel that can move forward and backward toward the groove on the outer circumferential surface of both propeller fans is provided, and a controller that controls the energization of the motor and the forward and backward movement of the rotating transmission wheel allows the first propeller fan to be driven by the motor. An air blowing fan device that controls the rotation and stopping of the first propeller fan and the transmission of the rotational force of the first propeller fan to the second propeller fan.
