Problems solved by technology

[0005] In the conventional slide-operated variable resistor disclosed in Patent Document 1 mentioned above, since the boss of the slider is pressed into the mounting hole of the sliding element, no gap between the mounting hole and the boss is required. However, there is a possibility that the boss is pressed in eccentrically with respect to the slider, so there is a problem that the installation position of the sliding element relative to the slider is offset due to the eccentricity, resulting in an error in the output signal

Abstract

A sliding operation type variable resistor has high output signal accuracy, in which the sliding element will not bias relative to the mounting position of the slide rod. An opening (43) is provided near one end of the length direction (slide rod moving direction) of the base (41) of the sliding element (4), thus, a stenosis portion (41a) if formed between the opening (43) and the one end. A clampprotuberance (41b) projecting to the opposite side of the opening (43) is formed on the stenosis portion (41a). A first restriction portion (restriction wall) (33) and a second restriction portion (restriction convex wall) (34) in contraposition with specified interval along the slide rod moving direction are provided on the slide rod (3), the base (41) is installed between the two restriction portions (33,34), and the specified interval is shorter than the natural length of the base (41), and the base (41) is clipped between the two restriction portions (33,34) when the restriction portions(33,34) are bent to the opening (43).

Description

technical field [0001] The invention relates to a sliding operation type variable resistor, in particular to an installation structure of a sliding element installed on a sliding block and in sliding contact with a resistor body and a current collector. Background technique [0002] The slide-operated variable resistor changes the contact position between the sliding element mounted on the slider and the resistor by sliding the slider linearly along the side of the substrate on which the resistor and the current collector are arranged side by side. In order to change the output resistance value, the existing widely used installation structure is to insert the synthetic resin boss provided on the slider into the installation hole provided on the sliding element, and perform riveting, so that the sliding element is fixed on the sliding element. on the block. However, this mounting structure has an unreasonable situation in that a gap is required between the mounting hole and ...
