じる。Problems to be Solved by the Invention As shown in FIG. 4, for example, when the belt contact angle of the pump pulley 4 is small, an idler pulley 9 is disposed between the pump pulley 4 and the P-S pulley 3. However, it is necessary to press the idler pulley 9 against the first drive belt 5 to ensure a required belt contact angle. When the idler pulley 9 is arranged in this way, the alternator pulley 6 is placed upwardly or downwardly on the front side of the idler pulley 9 so as not to overlap the idler pulley 9 in the pulley direction, as shown by the solid line or chain line in FIG. It becomes necessary to offset the position. As a result, when the alternator pulley 6 is placed upward, the height of the engine hood F becomes higher, as shown by the solid line in the figure.
In addition, when the alternator pulley 6 is placed downward, the height of the engine hood F can be lowered as shown by the chain line in the figure, while the runner R is moved from the solid line position to the chain line position in the figure. Shifting it forward increases the front-to-back length of the enron room, and in either case, this greatly restricts the degree of freedom in shaping the front of the vehicle body. Furthermore, since the alternator of the wave body is moved far from the center of gravity of the power plant, it is not only disadvantageous when it comes to vibration-proofing measures for the power plant, but also Since the driven body is likely to resonate, there is an inconvenience that the strength of the mounting bracket must be made higher than necessary.

The present invention provides a drive device for the following.

行える利点がある。According to the above embodiment, the auxiliary pulley 47 installed on the rotating shaft 16 of the alternator pulley 6 is placed between the P/S pulley 3 and the pump pulley 4. Therefore, the arrangement position of the alternator, which is the driven body of the alternator pulley 6, is
The P-S pulley 3 can be arranged close to the engine 11 between the driven bodies of the pump pulley 4. As a result, as shown in FIG. 3, the height above the ground of the engine hood F can be lowered, and there is no need to move the radiator R forward, and the engine room does not become too long. Then, as shown above, the auxiliary parts are attached to the engine 11.
Since these auxiliary parts can be arranged compactly around the engine 11 and transmission 12, these auxiliary parts can be moved closer to the center of gravity of the power plant 10, which consists of the engine 11 and the transmission 12, making it advantageous to take anti-vibration measures for the power plant 10. This has the advantage that it is possible to take measures to prevent resonance of the auxiliary equipment parts themselves.

る。Effects of the Invention As described in the second aspect, according to the present invention, the auxiliary pulley provided on the rotating shaft of the driven pulley of at least one of the plurality of auxiliary equipment parts is connected to another driving pulley adjacent to the auxiliary pulley. Since it is pressed against the belt and acts as an idler pulley, the installation position of the auxiliary equipment component can be lowered and closer to the engine side (
] This allows the auxiliary parts to be placed centrally around the engine, resulting in a compact layout. As a result, the degree of freedom in shaping the front of the vehicle body can be increased without increasing the height of the engine hood or increasing the front-rear length of the engine room or the width of the vehicle. In addition, since the dimensions between each of the auxiliary parts and the center of gravity of the power unit can be narrowed, it is possible to advantageously take anti-vibration measures for the power plant and anti-resonance measures for each auxiliary part, which has practical effects. It's a huge amount.
