To facilitate mounting of an oil cooler and a cooling fan. An oil cooler
which is a cooler and a cooling fan are accommodated in the same case to
form a cooling unit. This case is divided into a lid on the front half
portion side and a fan cover on the rear half portion side, and the oil
cooler is accommodated in the lid while the cooling fan is accommodated in
the fan cover. The two members are put together from the front and the
rear and are integrated with each other by means of fastening screws.
Suspending projections project on the left and right of an upper face of
the lid, and are attached to upper pipes, which are part of a vehicle body
frame, through suspending brackets. Further, the oil cooler is
accommodated in the lid in a state wherein damper rubber members are
applied to four corners thereof. Consequently, the damper rubber members
function as a rubber mounting structure in a non-coupled state wherein
they are merely interposed between a joint recess and the oil cooler.
