The core and the coil are disposed between the flywheel rotor and the engine. The fan is attached onto the flywheel rotor. The cover member is disposed above the fan. The cover member includes a first suction port that sucks in air from above the cover member. The flywheel rotor includes a second suction port that sucks in air from below the flywheel rotor.
