Abstract
A highly sensitive load detection device includes a tubular peripheral wall portion; a disk-shaped disk portion that has a through hole formed coaxially with the peripheral wall portion and that is supported on an inner surface of the peripheral wall portion with a gap between the disk portion and a placement surface on which the peripheral wall portion is placed; a load input portion that is formed in a spherical shape having a diameter larger than an inside diameter of the through hole on at least a side thereof facing the through hole, that is placed on the through hole, and to which a load of an object to be detected is input; and sensors that are provided on the disk portion so as to be point-symmetric about the through hole, and that detect a strain corresponding to the load input to the load input portion.
