Front vehicular body structure

Abstract

The present invention provides a vehicle body front part structure for surely absorbing shock load before an engine transmission unit hits on left and right front side frames. In this structure 10, left and right center mounting brackets 37 and 38 are provided at rear portions 22b and 26b forming a shock absorbing part 35. Each of the left and right center mounting brackets 37 and 38 is separably connected to a portion between front end part and rear end part of the front sub-frame 16. When shock load F1 is applied, the left and right center mounting brackets 37 and 38 are separated from the front sub-frame 16, and the separated brackets 37 and 38 are crushed by the engine transmission unit 15.
