The frame is as shown in FIG. 1 and FIG. 6 tf 'in the sliding type variable resistor crying in this embodiment' the driving body 8 may be in the frame body 1 made of a metal plate and used to plug the 哕: the bottom of the body 1 The body formed of the insulating substrate 4 with the bottom surface open is held in a slidable manner, and the cutout 3 on the side plate 1b of the control frame 8 of the driving body 8 and the frame 1 protrudes outward. Hereinafter, each structure constituting the slide-type variable resistor will be described in detail in order. The τ frame 1 is a rectangular box shape with a lower opening forcibly formed by a metal plate. The right and left sides of the upper plate la are provided with a pair of right-angled curved side plates lb. The side plates lb are projected downward from their lower ends. There are 5 mounting feet 2 extending on the left and right sides. It can be clearly seen from FIG. 4 to FIG. 9 that a pair of mounting feet 2 on the side plate 丨 b on the right side (the large-out side of the control lever 8a) is provided with a rectangular cutout 3 whose lower end is opened. As shown in FIG. 6, the middle portions of the mounting feet 2 are respectively provided with locking claws 2 a perpendicular to the extending direction of the mounting feet 2 on the i- and J-planes. In addition, the pair of locking claws 2a on the right side plate 丨 b protrude in the direction of the notch 3, and are arranged opposite to the notch 3 in the vertical direction. In addition, as shown in FIG. 3, on the left side (opposite to the protruding side of the control lever 8a) of the side plate 1b on both sides of the pair of mounting feet 2 are respectively provided with locking claws 2a having the same shape as the aforementioned locking claws, and The front ends of the pair of mounting legs 2 on the two sides are bent at a right angle toward the outside of the plate surface. In addition, when the frame body 1 is placed in a single state, if the insulating plate 4 is loaded on the frame body 1, the plate surface of the aforementioned clamping claw 2a perpendicularly intersects with the plate surface of the insulating substrate 4, as shown in FIG. In the actual use state, the locking claw 2a is bent so that the upper side of the locking claw 2a moves along the bottom surface of the insulating plate 4. The locking claw 2a and the lower ends of the plates ib on both sides of the frame 1 clamp and fix the insulating plate 4. live. In addition, the locking claws are formed in a conical shape having a smaller root thickness than the base plate and a slightly larger front end, so that the insulation plate 4 can be held in the gap between the locking claws 2 and both sides without being loosened when bent. The insulating plate 4 is made of an insulating material such as phenol resin or glass epoxy resin. As shown in FIG. 1, a total of 4 through holes 4 a are formed at both ends, and 2 at each end. The substrate is formed of carbon ink and the like. The resistance pattern 5 and the current collecting pattern 6 are fixed at the two ends of the insulating plate 4 through the cylindrical portion 7a into the through holes 乜, and the four terminals 7 are fixed. And one end of the current collecting pattern 6 are electrically connected. As shown in Figs. 3 and 4, the insulating plate 4 is clamped and fixed at the lower ends of the two inverted plates ^ by the locking claws 2a bent along the lower surface of the insulating plate 4, and together with the frame body 1, the above body is constituted. The driving body 8 is formed of an insulating synthetic resin material, and a sliding element 9 is fixed to the lower surface of the driving element 8. The sliding element 9 is made of a metal flat plate with a pair of sliding pieces. A right side of the driving body 8 is provided with a control lever which is integral with the driving body 8 and a rectangular shutter ig is provided on the control lever 8a. As shown in Figs. 5 and 6, the fan driver 8 slides the resistor pattern 5 and the current collecting pattern 6 formed on the slider 9 to the slider 9 to control the correction from the right side plate 1b. The notch 3 protrudes to the outside, and can slide freely in the body composed of the frame body and the insulating substrate 4 described above, and the cover 10 can cover the notch 3 regardless of the sliding position of the driving body 8. The basic structure of the slide-type variable resistor in this embodiment has just been explained, and the working principle will be described below. FIG. 10 shows a plan view when the slide-type variable resistor is incorporated in a circuit board, and FIG. 1 丨 is a cross-sectional view taken along line 1 1 -11 in FIG. 10. This sliding variable resistor is generally used in various electronic devices, such as small portable electronic devices such as video cameras. As shown in Figs. 10 and 11, two of the side plates lb on the right side of the housing 1 are mounted. Foot 2 and the unbent 1 mounting foot 2 on the left side plate ib are respectively embedded in the 3 foot gaps Π a on the circuit board 1 丨 installed in the device, and these mounting feet 2 are passed under the correct positioning state. The soft soldering method is welded to the two mounting feet 2 and the four terminals 7 bent on the left side plate lb, and is thereby mounted on the surface of the circuit board. In addition, a predetermined voltage is added from the circuit board 丨 丨 to both of the resistance pattern 5 through the terminal 7. When the operator operates the control lever 8 a with the finger in the direction of the arrow A, the driving body 8 will be driven by the side plates lb of the frame 1 Guide and slide in the body, a pair of sliding contacts 9a changes the conductive position of the resistance pattern 5 and the current collecting pattern 6, and an output signal corresponding to a voltage corresponding to the change in the conductive position will be a terminal connected to the greedy pattern 6. It is sent in 7 and the output signal thus obtained is transmitted to the circuit board Π, and then various settings and controls of the electronic device are performed. In the slide-type variable resistor described above, since the mounting feet 2 for positioning and fixing the main body (main body) on the circuit board are extended to form the locking claws, the locking claws in the conventional technology can be eliminated. The space between the 23 and the mounting leg 29 is 594800 ′, and the size of the mounting leg 2 and the locking claw 2a in the arrangement direction (direction of arrow a) can be reduced to achieve the purpose of miniaturization. In addition, the mounting leg 2 is arranged near the right side plate 1 b of the frame 1 where the control lever 8 a of the driving body 8 protrudes. Therefore, the locking claw 2 a of the mounting leg 2 can support the operation lever 8 a. Excessive load applied to the insulating plate η at the time, to prevent deformation or breakage of the insulating plate 11 due to excessive load, and to protect the contact stability pattern 5 and the current collecting pattern 6 and the contact stability of the sliding sheet. The mounting leg 2 on the right side plate 1b is provided with a locking claw 2a protruding to the side of the notch 3, so it can fully resist the above-mentioned excessive load and fully prevent the deformation and damage of the insulating substrate 11. In addition, the locking claw 2a and The notch 3 is opposite to the up-and-down direction, and a locking claw can be arranged inside the control talent 8a and the moving area (the width in the direction of the arrow A of the notch 3).
