Abstract
A propeller attaching device includes a coupler that rotates integrally with an output shaft of a motor, a movable body, and a resilient body. The coupler allows attachment/detachment of an attachment portion of the motor by rotation of the propeller in the circumferential direction and restricts the movement of the propeller in an axial direction. The movable body includes a second receiving portion, and is supported by the coupler so as to be movable in the axial direction. The attachment/detachment position is a position where attachment/detachment of the attachment portion to/from the first receiving portion is allowed. The restriction position is positioned in a first direction relative to the attachment/detachment position, the first direction extending from the other end to one end of the output shaft in the axial direction of the output shaft, and restricts the rotation of the propeller in the circumferential direction relative to the base.
