PURPOSE:To assemble each part without abnormally deforming a brush by forming an inclined section inclined in the direction separate from the brush with approach to the inserting port side to a resistor inserting port side end section in the groove section of a box-shaped case. CONSTITUTION:In a linear type rheostat, in which a brush mounting plate 22 slidable in the linear direction, a linear type resistor 24 inserted and installed in the same direction as the brush mounting plate 22 along a groove section formed to a box-shaped case 21 and a brush 23 set up to the brush mounting plate 22 so that a nose thereof is brought into contact with the resistor 24 are disposed into the box-shaped case 21 composed of an insulating material respectively and a resistance value of which is changed by moving a shaft 30 fitted to the brush mounting plate 22 in a projecting and retreating-free manner to the box-shaped case 21, an inclined section 21f inclined in the direction separate from the brush 23 with approach to the inserting port side is formed to a resistor inserting-port side end section in the groove section of the box-shaped case 21. Accordingly, the resistor can be incorporated into the box-shaped case without abutting an edge section thereof against the brush, thus preventing the deformation of the brush.
