付けられている。 FIG. 1 shows an external side view of a conventional orthogonal sliding type variable resistor, in which 1 is an insulating substrate, and 2 is a rectangular shape fixed to the insulating substrate 1 by a plurality of mounting legs 2a. It is a case, and 3 is a lever protruding from a long groove provided in the center of the upper surface of the case. A slider is attached to this lever 3 for conveying a slider (not shown) that slides into contact with the insulating substrate 1 inside the case 2.

た。 However, in the conventional variable resistor described above, the sliding path and the slider are relatively long, and the adjustment mechanism in which a plurality of such variable resistors are arranged in parallel and interlocked,
For example, in a slide volume with two levers,
When manually transporting the slider using the lever 3 and placing it at a predetermined adjustment position, the sliding path is long and the slider is also vertically long, so the sliding movement within the slider case 2 is unstable, and the predetermined adjustment is difficult. There were drawbacks such as interlocking errors caused by not being held still in position.

するネジ（図示せず）逃げ用のものである。 To explain the structure of the slider of the present invention in FIG. 2, 4 is a substantially box-shaped slider molded from an insulating molded material such as synthetic resin, and a lever 3 protrudes from the top surface and a pair of protrusions from the bottom surface. A slider 6 is attached to 4b by caulking or the like. 4a
4c are sliding legs provided at the four corners of the slider 4 in the vertical direction, and 4c is a notch provided at the opposite sliding end of the top surface of the slider. It is for use.

ライダー４が静止し、多少の振動などによつてこ
の静止位置が乱されることはない。 Reference numeral 5 denotes an elastic piece integrally formed with the slider 4 between the pair of sliding legs 4a on one side of the slider 4, which includes a holding portion 5b projecting horizontally at right angles from the center of the side surface of the slider 4; A pair of elastic arms 5c extend in a bifurcated manner from the holding portion through a notch 5e to slide opposite the slider 4, and a pair of elastic arms 5c are formed at the tips of the elastic arms 5c via a constricted portion 5d. The elastic arm 5c expands slightly outward from the holding part 5d, and the sliding locking piece 5a also extends from the elastic arm 5c.
The elastic locking piece 5a is arranged so as to be slightly inclined with respect to the sliding leg 4a, and the elastic locking piece 5a is normally located outside the sliding leg 4a as shown in the figure. FIG. 3 shows the back side of the slider 4 stored in the case 2. In this case, the entire slider 4 is attached to the elastic arm 5.
The elastic locking piece 5a is always pressed in one direction with an equal force by the elastic force of c, and the elastic locking piece 5a is always brought into elastic contact with the inner wall of the case 2. Therefore, when the lever 3 protruding outward from the long groove 2b on the upper surface of the case 2 is manually moved in the direction of the arrow, the corresponding slider 4 is also conveyed within the case 2 to a predetermined adjustment position while maintaining the above-mentioned stable posture. When the lever 3 is released, the slider 4 is stopped at this predetermined position by the elastic locking piece 5a, and this resting position is not disturbed by slight vibrations.

る。 According to the present invention described above, the sliding movement of the slider 4 is stable and the adjusted position is accurately maintained, so that it is possible to easily prevent the occurrence of interlocking errors.Moreover, the elastic piece 5 is molded integrally with the slider 4. Therefore, there is no need to add any parts, and when loading the slider 4 into the case 2, the elastic piece 5
Since the slider 4 has a temporary fixing function, it prevents the slider 4 from falling out of the case 2 during assembly, and has many practical advantages, such as improving assembly workability.
