Abstract: A torque sensor includes a first structure, a second structure, a third structure provided between the first structure and the second structure, and at least two sensor units provided between the first structure and the second structure. A plurality of first contact portions having a structure integrated with the first structure is provided inside an outer peripheral portion of the first structure, first distal ends are arranged near the outer peripheral portion, and the first distal ends are in contact with a first attachment portion. A plurality of second contact portions having a structure integrated with the second structure is provided at a part of an inner peripheral portion of the second structure, second distal ends are arranged near the inner peripheral portion, and the second distal ends are in contact with a second attachment portion.

Abstract: The object is to provide a mounting structure for a torque sensor capable of improving a detection accuracy of a torque sensor. A torque sensor includes a first structure, a second structure, a third structure provided between the first structure and the second structure, and at least two sensor units provided between the first structure and the second structure. A plurality of contact portions are provided on one of the first structure and the first attachment portion and one of the second structure and the second attachment portion, and are in contact with another of the first structure and the first attachment portion and another of the second structure and the second attachment portion.

Abstract: An elastic body is fixed to a main body and a movable body and is deformable according to the movement of the movable body. A strain sensor is provided on the elastic body and includes a strain body. The movable body includes an opening. The stopper member includes a first contact portion and a second contact portion provided inside the opening, whose distances from the opening are different from each other. The first contact portion is located in a direction in which the movable range of the strain body is great, and the second contact portion is located in a direction in which the movable range of the strain body is small.
