1. A load detection device for a vehicle seat, comprising:
- a strain generating body including a first end hole at a first end portion of the strain generating body and a second end hole at a second end portion of the strain generating body, and a strain gauge being attached on the strain generating body between the first end hole and the second end hole;
a first fixing member including a first middle shaft portion press-fitted into the first end hole and a first end shaft portion protruding from the first middle shaft portion, the first fixing member being configured to be connected to one of a seat-side fixing member fixing the vehicle seat and a floor-side fixing member fixing the seat-side fixing member to a floor of the vehicle;
a second fixing member including a second middle shaft portion press-fitted into the second end hole and a second end shaft portion protruding from the second middle shaft portion, the second fixing member being configured to be connected to the one of the seat-side fixing member and the floor-side fixing member;
a bracket member including a connecting portion and first and second fixing portions connected to each other with the connecting portion, the bracket member including a first fixing hole at one of the first and second fixing portions and a second fixing hole at the other one of the first and second fixing portions, the first fixing hole being formed in a manner that the first end shaft portion of the first fixing member is configured to be press-fitted into the first fixing hole, the second fixing hole being formed to be fitted onto the second end shaft portion of the second fixing member in a manner that the second fixing hole includes a degree of freedom of a movement of the second fixing hole relative to the second end shaft portion of the second fixing member in a lengthwise direction of the strain generating body and in a manner that a movement of the second fixing hole relative to the second end shaft portion in a direction intersecting with the lengthwise direction is restricted; and
a connecting member integrally connected to a center portion of the strain generating body and connected to the other one of the seat-side fixing member and the floor-side fixing member.
