PROBLEM TO BE SOLVED: To provide a contact force/frictional force measuring device capable of measuring a contact force and a frictional force acting between a first contact part and a second contact part, while applying a current between the first contact part and the second contact part.SOLUTION: When a contact force Fvaries and a simulation slider Pis minutely displaced in the direction of Aand A, a load F' almost equal to the contact force Facts on a load detection part 9, and the load F' is detected by the load detection part 9. Further, when a frictional force Fvaries and a test piece Pis minutely displaced in the direction of Band B, a load F' in the direction of action of the frictional force Facts on a load detection part 11, and the load F' is detected by the load detection part 11. As a flexible electrically-conductive part 14 for applying a current to the simulation slider Pand a simulation trolley wire Pis connected to a load transmission part 4, the weight and resistance force of the electrically-conductive part 14 act on the load transmission part 4, whereby occurrence of a measurement error in the contact force Fand the frictional force Fcan be prevented to the extent possible. |
