    • PROBLEM TO BE SOLVED: To provide a method and a structure of vibration isolation support of a cooling fan cover forming a casing of a fan supplying cooling air to a forcedly air-cooled engine. SOLUTION: In a cooling fan cover for the forcedly air-cooled engine having a structure directly fixed on a cylinder block by bolts at a plurality of fixing leg parts provided on a circumference edge, soft vibration isolator is fitted in the fan cover circumference edge to prevent generation of noise or the like due to vibration of the fan cover having a nod on the leg part caused by resonance with vibration generated by the cylinder block, margin a little bit smaller than thickness of the soft vibration isolator is provided on the fan cover circumference edge, a narrow flange is provided on an end surface forming the margin, the soft vibration isolator is retained by making the end surface and the flange fit in a T-shape groove formed in the soft vibration isolator, and vibration and contact pressure due to press contact are reduced.

    • PROBLEM TO BE SOLVED: To effectively utilize cooling air circulated by a fan 31 for heat exchange in a cooling device for a vehicle in which a part of the fan 31 is positioned at a position out of a projection plane of a radiator core 11 when seeing from a front side of the vehicle.
      SOLUTION: A capacitor core 21 is arranged at a front side of the fan 31 positioned at a position out of the projection plane of the radiator core 11 and a shroud 4 is extended to a capacitor core 21 side than the radiator core 11. Thereby, even if the part of the fan 31 is positioned at a position out of the projection plane of the radiator core 11, since the cooling air circulated by the fan 31 is passed through at least one of the capacitor core 21 and the radiator core 11, the cooling air circulated by the fan 31 is effectively utilized for heat exchange.
