Claims

[Scope of utility model registration request]

Two resistors are mounted on the side surface of the casing at right angles to each other in a horizontal plane, and a brush shaft having a brush that contacts the resistance wire ring of each of these resistors is rotatably mounted. An operating member is provided with a sphere rotatably engaged in a three-dimensional manner with a concave spherical seat fixed at the center of the upper surface, an operating shaft passing through the sphere is fixed, and the brush shafts are fixed to each of the operating members. By respectively engaging the operating shafts through and tilting the operating shafts,
In the variable resistor in which the brush shafts are rotated simultaneously to change the resistance values of the two resistors at the same time, a hollow partial sphere having a radius R and having the same center as the sphere is joined to the upper end of the operating shaft; , an operating sphere having a radius r that is three-dimensionally rotatably engaged with a concave spherical seat fixed to a fixed part directly above the sphere and in contact with the hollow partial sphere, and the operating sphere can be operated with a fingertip. and thereby frictionally drive the hollow partial sphere, the variable resistor is configured to operate the operating shaft with its tilt angle reduced to a rotation center angle R of the operating sphere.
