As shown in Figure 8, driving engine 42 is equipped with the liquid-cooled engine of the radiator 45 of engine cooling water directly over cylinder body portion 44.
As Fig. 8, shown in Figure 9, dispose side cover 56,56 in the left and right sides of Fuel Tank 5, this side cover 56,56 is fixed in the side frame portion 12 and radiator 45 of head lamp supporter 1 by side cover fixed parts 58.
Figure 10 is the variation of embodiment of the present invention, uses the radiator 45 of the storagetank 59 replacement engine cooling waters of engine cooling water.That is, this driving engine 42 is equipped with the liquid-cooled engine of the storagetank 59 of engine cooling water directly over cylinder body portion 44.Storagetank 59 is the containers that store engine cooling water, and the engine cooling water in the storagetank 59 absorbs the heat of cylinder body portion 44 and gasifies.Other 26S Proteasome Structure and Function of this driving engine 42 is identical with the driving engine of Fig. 8, and member identical with the driving engine of Fig. 8 in Figure 10 marks same Reference numeral.
