A cowl grille comprises a member portion which extends in a vehicle width direction below a front windshield so as to receive water dripping from the front windshield, a cover portion which is positioned in front of a member portion and covers over an auxiliary equipment, a partition portion which extends downwardly from the cover portion and partitions a space where an engine is arranged from another space where the auxiliary equipment is arranged, and a cowl seal which extends in the vehicle width direction and contacts a bonnet so as to seal between a vehicle outside space and an engine room. The cowl seal is positioned at a front part of the member portion, and the cover portion is made of a plate member and provided to perform heat insulating between a space positioned above the cover portion and another space positioned below the cover portion.
