Vehicle structure of frame vehicle

A vehicle structure of a frame vehicle in which a body is mounted on a frame through a mount, the vehicle structure comprising:

• a central frame portion that is provided in a center portion of the vehicle structure in a vehicle front-rear direction and formed so as to be symmetrical in the front-rear direction;
• a front-side frame portion that is connected to a front end portion of the central frame portion and supports a front suspension;
• and
• a rear-side frame portion that is connected to a rear end portion of the central frame portion and supports a rear suspension, wherein:
• the central frame portion, the front-side frame portion, and the rear-side frame portion are provided as the frame;
• at least a section of the front-side frame portion from a connecting portion of the front-side frame portion to the central frame portion through a portion supporting the front suspension, and a section of the rear-side frame portion from a connecting portion of the rear-side frame portion to the central frame portion through a portion supporting the rear suspension are formed so as to be symmetrical to each other in the front-rear direction with respect to the central frame portion;
• and
• the front suspension and the rear suspension have the same shape and are attached to the front-side frame portion and the rear-side frame portion, respectively, so as to be symmetrical to each other in the front-rear direction with respect to the central frame portion, wherein:
• the central frame portion includes a pair of side rails, the side rails extending in the vehicle front-rear direction in both end portions of the central frame portion in the vehicle width direction, respectively, while the front-side frame portion and the rear-side frame portion include a pair of front side rails and a pair of rear side rails, respectively, the front side rails and the rear side rails extending in the vehicle front-rear direction at positions higher than the side rails, respectively, and on inner sides with respect to the side rails in the vehicle width direction, respectively;
• the vehicle structure comprising:
• front-side joint members that are connected to rear end portions of the front side rails, respectively, extend from the rear end portions of the front side rails, respectively, to a rear side in the vehicle front-rear direction so as to be inclined outward in the vehicle width direction and downward, and then are connected to front end portions of the side rails, respectively, the front-side joint members being formed separately from the central frame portion and the front-side and rear-side frame portions;
• and
• rear-side joint members that are connected to front end portions of the rear side rails, respectively, extend from the front end portions of the rear side rails, respectively, to a front side in the vehicle front-rear direction so as to be inclined outward in the vehicle width direction and downward, and then are connected to rear end portions of the side rails, respectively, the rear-side joint members being formed separately from the central frame portion and the front-side and rear-side frame portions;
• and
• the front-side joint member and the rear-side joint member are formed so as to have the same shape.
