A joint structure for a vehicle, the joint structure composing:

• a plate-shaped first member;
• a plate-shaped second member with substantially parallel external and internal edges, of which at least a portion is superposed with the first member in a plate thickness direction of the first member so that the external edge of the second member remains spaced from an external edge of the first member when viewed from the plate thickness direction of the first member;
• a plurality of crimped portions provided in a flat region at which the first member and the second member are superposed, the first member and second member being joined at the crimped portions by mechanical clinching from a side at which the first member is disposed;
• and
• a reinforcing portion provided at the first member, the reinforcing portion being inflected toward a substantially normal direction in a vicinity of the crimped portions, and a protruding portion of the reinforcing portion is spaced from both the external and internal edges of the second member such that the protruding portion of the reinforcing portion does not overlap the second member when viewed from the plate thickness direction of the first member.
