wherein a portion of the side-wall parts is comprised of an engine mount bracket configured to support a mount of the engine, instead of the dedicated heat retention member;
wherein the upper lid has no openings;
wherein the engine mount bracket includes a vertical wall extending in a longitudinal direction of the vehicle to be positioned adjacent to the side-wall parts of the dedicated heat retention member; and
wherein a lower portion of the vertical wall is attached to a frame of the vehicle, and an upper portion of the engine mount bracket is attached to the upper lid; and
wherein the side-wall parts are positioned between the upper lid and the frame of the vehicle.

2. The vehicle of claim 1 , wherein the engine mount bracket is attached to an upper surface of a front side frame of the frame at two, front and rear, attachment parts, and the vertical wall is formed in the engine mount bracket to cover a space between the front and rear attachment parts.

3. The vehicle of claim 1 , wherein the side-wall parts of the dedicated heat retention member are comprised of a resin member, and the engine mount bracket is comprised of a metal member, and
wherein the upper lid is placed on and supported by an upper surface part of the engine mount bracket.
