Claim Text:
1. A load detecting device comprising: a pin-type load cell; and a load calculating unit that calculates a load that acts on the pin-type load cell according to a detection signal output of the pin-type load cell, wherein the pin-type load cell includes a pin body provided with a pin hole in an axial direction, and three or more pairs of or three or more strain detecting units placed in a circumferential direction of the pin body, and the load calculating unit includes a selecting unit that selects, from among the three or more pairs of or three or more strain detecting units, a strain detecting unit that is less influenced by a change in a cross-sectional shape of the pin body, and a calculating unit that calculates a load that acts on the pin body based on a detection signal output of the strain detecting unit selected by the selecting unit.
