対策が十分であるとは云えない。The engine mount arrangement structure includes a front mount member 10, a rear mount member 11, and side mount members 12 and 13 on both sides.
However, it is said that the arrangement in a cross shape just in a plan view is effective for countermeasures against noise and vibration such as idle vibration, acceleration noise, and muffled sound. However, as described above, the side mount member 13 on the transmission 3 side avoids interference with the air cleaner 9, and therefore the side mount member 1 on the engine body 2 side.
Therefore, it is necessary to provide an offset arrangement ahead of the position 2, and it cannot be said that sound vibration countermeasures are sufficient.

ント部分の造形上支障を来してしまう。In order to align the side mount member 13 with the side mount member 12 in the front-rear direction, the position where the air cleaner 9 is disposed must be moved upward, which increases the ground height of the engine hood. This will hinder the modeling of the front part of the vehicle body.

する必要があってコスト的に不利となってしまう。Accordingly, as described above, the side mount member 13 must be disposed at the front portion of the side of the transmission 3 due to these circumstances. As a result, if only measures against sound vibration become insufficient, Instead, it is necessary to provide a reinforcing stay 15 as shown in FIG. 7 or to increase the thickness of the mount bracket 13a in order to counter the input during rolling of the power plant 1, which is disadvantageous in cost. .
