In FIGS. 1 and 2, a front plate 9 of a mounting bracket 7 (a left one of a pair of mounting brackets 7 is shown in FIGS. 1 and 2) is a shaft 1.
A base portion (hereinafter, referred to as a front plate base portion) 9b connected to a substantially rectangular portion (hereinafter, referred to as a shaft mounting portion) 9a to which the second member 2 is attached has a lower portion as compared with an upper portion as a vehicle. 1 protrudes forward (to the left in FIG. 1; obliquely downward to the right in FIG. 2);
b is inclined (the lower part is inclined so as to be in front of the vehicle 1 compared to the upper part). In the present embodiment, the front plate portion base end 9b forms an inclined plate portion (wind guide portion), and the mounting bracket 7 forms a front lower side arrangement member.

In FIG. 2, reference numeral 33 denotes a hole into which a fastening member such as a bolt is inserted. The mounting plate 8 is placed on the lower surface of the side frame 6 and inserted into the hole 23 formed in the mounting plate 8. The mounting bracket 7 is attached to the side frame 6 by a fastening member such as a bolt.

In the vehicle engine mount device thus configured, when the traveling wind hits the front end 9b of the front plate portion when the vehicle 1 travels, the front end 9b of the front plate portion transfers the traveling wind to the upper engine room. Guide to 3. The engine room 3 and the exhaust manifold 17 and the turbocharger 18 are driven by the traveling wind guided to the engine room 3.
