PROBLEM TO BE SOLVED: To provide a swing type power unit which protects an intake air temperature sensor while securing the volume of a cleaner case, in the swing type power unit which is configured by combining such a case cover that the cleaner case of an air cleaner is arranged on the car width direction one side of a rear wheel and a case main body of which at least a part is arranged between the case cover and the rear wheel and attaches an intake air temperature sensor for detecting an intake air temperature to the case main body.SOLUTION: A case main body 52 has a case main body main part 52a arranged on the car width direction one side of a rear wheel WR in a plane view and a swollen part 52b which is swollen from the case main body main part 52a to the car width direction other side while overlapping at least a part thereof to the rear wheel WR in one body, an intake air temperature sensor 78 is attached to the swollen part 52b so as to be protruded to the car width direction other side from the swollen part 52b, and a protective member 85 having a cover part 85a with which a part of the rear wheel WR is covered from the radial direction outer side is attached to the case main body so as to be arranged between the intake air temperature sensor 78 and the rear wheel WR in a lateral plane view.
【課題】エアクリーナのクリーナケースが、後輪の車幅方向一側に配置されるケースカバーと、ケースカバーおよび後輪間に少なくとも一部が配置されるケース本体とが結合されて成り、吸気温度を検出する吸気温度センサがケース本体に取付けられるスイング式パワーユニットにおいて、クリーナケースの容量を確保しつつ、吸気温度センサを保護する。【解決手段】ケース本体52が、平面視で後輪WRの車幅方向一側に配置されるケース本体主部52aと、平面視で少なくとも一部を後輪WRに重ねてケース本体主部52aから車幅方向他側に膨出する膨出部52bとを一体に有し、吸気温度センサ78が膨出部52bから車幅方向他側に突出するようにして膨出部52bに取付けられ、後輪WRの一部を径方向外側から覆うカバー部85aを有する保護部材85が、側面視で吸気温度センサ78および後輪WR間に配置されるようにしてケース本体52に取付けられる。【選択図】 図6
