BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of the embodiment of the present
invention, FIG. 2 is a sectional view taken along the line X-X in FIG. 1, and FIGS. 3 and 4 are slider
mounting plates 2 and 3 respectively. A and B are variable resistors opposed to each other, 1 is a
rotating shaft, 4 and 5 are respective resistive elements, 8 is a serration portion, and 9 and 10
are respective sliders. Fig.2 Fig.4 103-
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the construction
of two or more interlocking variable resistors. Interlocking variable resistors are often used for
stereo, in which case the resistance change characteristics of the respective resistors, 6% where
the mutual deviation is strictly required, should satisfy the user's requirements for the mutual
deviation It was very difficult. The reason is that in the case of opposed double variable resistors,
it is necessary to have logarithmic change characteristics, 1 / -47-21142-2 1 ------------ 11--one-one-- If they are arranged in the same way, they do not have the same shape but have a
symmetrical shape.] Therefore, it is necessary to make exactly the opposite change of the paper,
but in mass production this is difficult because it resonates. Therefore, when mutual deviation is
strictly required, it is absolutely necessary to mechanically adjust the change characteristics of
both and match the mutual change of both. An object of the present invention is to obtain a
single-shaft, two-station variable resistor that satisfies the above requirements with a simple
mechanism. Referring to the drawings, A and B are variable resistors facing each other. The
rotary shaft 1 penetrates them, and the sliding elements 9 and 10 slide on their respective
resistance elements 4 and 5 respectively. However, the slider attachment of the variable resistor
A is for the plate 2 and the slider attachment for the variable resistor B is for the thermoplastic
resin 4) and mount the foot 2 of the installation 1 [2] and fit the frame 7 on the upper side of the

mounting to adjust the mutual deviation of resistance elements 4 and 5 put a knob on the lower
end serration of plate 3 and fix mounting plate 2 with the rotation axis However, when the knob
is turned, only the plate 3 can be rotated for mounting. Furthermore, although the rotary shaft 1
has various shapes depending on the user's request and it has been a cause of confusion in the
manufacturing process, according to the present invention, the rotary shaft can be mounted after
assembly. Storage as a standard stock, and an axis enables combined shipping after user's
request. The present invention is mechanically structured so that the mutual deviation can be
adjusted with respect to the table which can be easily assembled and miniaturized in the opposed
single-shaft double-variable resistors as described above.
