Frame structure

A frame structure in a vehicle, the frame structure comprising:

• a front intermediate member that has four or more front through-holes and is provided such that a longitudinal direction of the front intermediate member coincides with a width direction of the vehicle;
• a rear intermediate member that has four or more rear through-holes and is provided behind the front intermediate member such that a longitudinal direction of the rear intermediate member coincides with the width direction of the vehicle;
• a first front side member that is fixed to a first front through-hole of the front intermediate member in a state of being inserted in the first front through-hole and extends forward from the front intermediate member;
• a second front side member that is fixed to a second front through-hole of the front intermediate member in a state of being inserted in the second front through-hole and extends forward from the front intermediate member;
• a first rear side member that is fixed to a first rear through-hole of the rear intermediate member in a state of being inserted in the first rear through-hole and extends rearward from the rear intermediate member;
• a second rear side member that is fixed to a second rear through-hole of the rear intermediate member in a state of being inserted in the second rear through-hole and extends rearward from the rear intermediate member;
• a first intermediate side member that is fixed between the front intermediate member and the rear intermediate member in a state of being inserted in a third front through-hole of the front intermediate member and a third rear through-hole of the rear intermediate member;
• and
• a second intermediate side member that is fixed between the front intermediate member and the rear intermediate member in a state of being inserted in a fourth front through-hole of the front intermediate member and a fourth rear through-hole of the rear intermediate member, wherein
• the positions of the first front through-hole and the second front through-hole in the longitudinal direction of the front intermediate member are closer to a center of the vehicle than the positions of the third front through-hole and the fourth front through-hole in the longitudinal direction of the front intermediate member,
• the first intermediate side member includes a first reinforcing member provided at least one of above or below a linear first base member,
• the second intermediate side member includes a second reinforcing member provided at least one of above or below a linear second base member, and
• a width of the first intermediate side member and a width of the second intermediate side member in the height direction of the vehicle in a region between the front intermediate member and the rear intermediate member are larger than a width of the first intermediate side member and a width of the second intermediate side member in the height direction of the vehicle in a region in front of the front intermediate member and behind the rear intermediate member.
