PROBLEM TO BE SOLVED: To enable measuring an input load while avoiding an increase of dummy weight by installing a flat-circle like fluid pressure sensor in contact with an elastic member placed between joint members. SOLUTION: A shoulder part 6 of a dummy, which is placed between a rigid body 8 and an arm part 9 provided in a trunk part, is constituted with a first joint member 10 rotably connected to the rigid body 8 and a second joint member 11 rotably connected to the first joint member 10. An elastic member 12 of rubber is placed between the rigid body 8 and the joint member 10 and an elastic member 13 is placed between the joint members 10, 11. Then, a pair of flat circle like fluid pressure sensors 17, 17 contacted to both end faces of the elastic member 12 are installed. Also, a flat-circle like fluid pressure sensor 18 contacted to the elastic member 13 is installed. That is, a load acting on the elastic members 12, 13 is measured by treating the members 12, 13 in conformance with fluids like liquid.
