A power transmission switching device includes a power shaft that is rotationally driven, a power transmission unit that is displaced between first and second positions positioned in an axial direction of the power shaft, a first positioning member that positions the power transmission unit in the first position, and a second positioning member that positions the power transmission unit in the second position. Any one or both of the switching of the connection and non-connection between the power shaft and the power transmission unit and the switching of the connection and non-connection between the power transmission unit and a driven part using the power shaft as a power source are performed by the switching of the position of the power transmission unit. The power transmission unit has at least one middle position between the first and second positions, and is held in the middle position by a holding unit.
