Load sensor
First Claim
1. A load sensor disposed between a first member and a second member to detect a load applied to the first member in an up-down direction, the load sensor comprising:
- a strain body including a strain gauge;
a first fixation member fixing the strain body and the first member to each other;
a second fixation member fixing the strain body and the second member to each other; and
a restriction portion restricting a displacement of the strain body in a state where the first member is displaced upward by a predetermined distance relative to the second member based on the upward load applied to the first member,wherein the restriction portion includes a first restriction member disposed between the strain body and the first member and including a first folding-back portion and a second restriction member disposed between the strain body and the second member and including a second folding-back portion, the first folding-back portion and the second folding-back portion being positioned in an alternating manner so that the second folding-back portion makes contact with the first folding-back portion in a case where a relative position of the second folding-back portion in the up-down direction relative to the first folding-back portion is displaced by the predetermined distance by a load applied to the first member in the up-down direction.
