1. A working vehicle, comprising: a power source unit; an electrically-driven motor that operates with electrical power from the power source unit;a traveling transmission system to which motive power of the electrically-driven motor is transmitted;a cabin in which a driver rides and that has a roof portion;an air intake passage through which air outside the cabin is supplied to the power source unit; and an air exhaust passage through which air supplied to the power source unit is exhausted out of the roof portion;wherein the power source unit, the air intake passage, and the air exhaust passage are arranged inside the roof portion, the power source unit is disposed in a portion close to a center in a vehicle body width direction, the air intake passage guides air taken from an air intake port that is provided in a center portion in the vehicle body width direction, to the power source unit, and the air exhaust passage is bent in a planar view such that air supplied to the power source unit flows in a bent manner toward an air exhaust port that is provided in one end portion in the vehicle body width direction. 2. The working vehicle according to claim 1, wherein the roof portion has a projection portion that is projected outward in the vehicle body width direction from the cabin in a planar view, and the air exhaust port exhausts air downward in the projection portion of the roof portion. 3. The working vehicle according to claim 1, wherein the roof portion is provided with an air conditioning apparatus that supplies air-conditioned air to the cabin, the air conditioning apparatus is disposed in a portion close to the center in the vehicle body width direction behind the power source unit in a vehicle body front-to-rear direction, and the air exhaust passage is bent away from the air conditioning apparatus in a planar view. 4. The working vehicle according to claim 3, wherein air-conditioned air supply passages that supply air-conditioned air whose condition has been altered by the air conditioning apparatus to the cabin are provided in both end portions in the vehicle body width direction of the roof portion, a support member that supports the power source unit is positioned between the air-conditioned air supply passages so as to be lower than an upper end portion of the air-conditioned air supply passages in a planar view, and the power source unit is supported on an upper portion of the support member. 5. The working vehicle according to claim 1, wherein the roof portion has an inner roof and an outer roof, the outer roof is placed so as to cover an upper portion of the inner roof, so that a space for accommodating the power source unit is formed between the outer roof and the inner roof, and the air intake port and the air exhaust port are arranged in the outer roof, the air intake passage has an inner channel section that is disposed on the inner roof side and an outer channel section that is disposed on the outer roof side, the air exhaust passage has an inner channel section that is disposed on the inner roof side and an outer channel section that is disposed on the outer roof side, and when the outer roof is placed so as to cover the upper portion of the inner roof, the inner channel section and the outer channel section of the air intake passage are connected to each other, and the inner channel section and the outer channel section of the air exhaust passage are connected to each other. 6. The working vehicle according to claim 5, wherein a connecting portion between the inner channel section and the outer channel section of the air intake passage and a connecting portion between the inner channel section and the outer channel section of the air exhaust passage are inclined with respect to a placement direction in which the outer roof is placed on the upper portion of the inner roof. 7. A working vehicle, comprising; a passenger cabin including a roof, the roof comprising: a power source disposed at a location substantially central with respect to a left and right direction of the roof;an air intake port disposed at a location substantially central with respect to the left and right direction of the roof;an air intake passage configured to connect the air intake port to the power source, the air intake passage being configured to take air from an outside of the roof into the power source,an exhaust port disposed at a side of the roof; andan air exhaust passage configured to connect the air exhaust port to the power source, the air exhaust passage being configured to exhaust air from the power source to the outside of the roof, the air exhaust passage being configured to bend towards the air exhaust port such that an air supply to the power source flows towards the air exhaust port.
