Abstract

PURPOSE:To put an engine at the lower position so as to facilitate the lowering of the center of gravity by mounting the engine on the strut bar for coupling the tops of the right and left suspension towers of a vehicle where the engine is placed longitudinally. CONSTITUTION:Mount brackets 3, each of which extends in the longitudinal direction of the car body, with its one end coupled with the strut bar 1 extending in the direction of car width with both its ends coupled with the tops of the suspension towers provided at right and left of the car body, and with its rear end coupled with a dash board, are provided in roughly parallel at a specified interval. An engine mount 4 is provided below this mount bracket 3, and an engine 6 to constitute a power train is placed longitudinally, being slid to the side from the axis of the crank shaft. Accordingly, the engine can be placed in the lower position, and also the installation space for a kind of auxiliary can be secured, and the design of the mounting of the engine can be facilitated.
