PURPOSE:To reduce the number of wirings by providing an elastic layer along on a Hall element to the base fitting a Hall element, providing a magnetized layer on the surface of the layer thereof corresponding to Hall element and by covering these with a protecting cover. CONSTITUTION:The robot gripper applying this invention is equipped with a pair of parallel finger parts 1 and a motor 2 for driving the finger parts 1, 1. And for a power detecting element 3, for instance, a Hall element 5 is fitted to the inner part of the supporting part, which is a plate material 4 formed to a hollow cylindrical shape. A elastic layer, for instance, an elastic body 6 of plate shape of a rubber, etc. is provided along the Hall element 5 on the plate material 4 thereof and a magnetized layer of the ink 7, etc. containing a magnetized magnetic body is coated on the portion corresponding to the Hall element 5 of the surface of the elastic body 6 thereof, and at the front face side of the elastic body 6 thereof, for instance, a plate shaped protecting cover 8 formed with a polymeric material is provided. |
