| 摘要 |
A force detection device of the present invention includes a handle to be given an operation force by an operator, disposed on a support reciprocatably in a first axis direction along a forward/backward direction of the truck and a second axis direction orthogonal thereto. A pair of force detection parts capable of detecting only a force in the first axis direction is disposed on the support in a spaced-apart relationship in the second axis direction. A force propagation body intervenes between both force detection parts and the handle. A part of the force propagation body passes through the inside of a gripped part of the handle. The force propagation body is coupled to the handle by a coupling axis extending in a third axis direction orthogonal to the first axis and second axis so as to be capable of relative rotation about the coupling axis.
