【Detailed description of the invention】 Pre-IK made of a small plastic resin suitable for
relatively small knees such as hw4 hw 聾 ^ ^ ^ ^ 1 1 1 可 1 可I am concerned about the selfgoverning hand. For example, the volume adjustment knob on the front face of the stereo in the
stereo image box and the variable element such as a capacitor made of aluminum and the like
which is changed by the rotation operation of the knob are positionally oriented with each other
It is often provided in a misaligned state. Conventionally, in such a case, a well-known gold-made
universal joint has been mainly used as a two-way linkage, but according to this conventional
universal joint, there are the following drawbacks. ■ Even conventional joints, even those made
of pure pure water, have a large number of parts, such as two sets of claws, -1 plaster, and a set
screw, in addition to balls, making production and assembly troublesome. Therefore, the
assembly operation is complicated, and there is a high possibility that the product performance
may vary depending on the quality of the assembly operation. @ Depending on the use site of the
joint, etc., although it is often the case that it is desirable to perform some processing such as
scraping the joint 1a or cutting a grooved pipe, the work is difficult- ■ As mentioned above (, the
number of parts is great, manufacturing and assembly are lyrical, so the cost is quite an island
due to change 3. The purpose of the present invention is to eliminate the above-mentioned
various drawbacks, and the purpose is to reduce the number of parts (the production and
assembly are easy and the cost is not large and the cost is reduced). There is to offer. The
assembly is as follows. In the present invention, a pair of opposing claw-shaped pieces are
integrally connected to a tip #, and an axial hole is provided in the claw-shaped pieces. Made of
synthetic resin, which is large enough to be loosely attached to each of the claw-like pieces, and
has four supporting shafts fitted to the front-side feeding shaft projecting at four places on its
peripheral surface so as to be orthogonal to a cruciform Medium I% I! Each main shaft of the
intermediate node is fitted into the axial hole of the independent body by using the nature of
each nail piece, and the main body is It is a synthetic resin free joint that is connected to the
middle node in a posture of 90 cLrtN so that the claw pieces are engaged with each other.

(5) is a variable element provided in the stereo main body: a variable element such as an
aluminum complex, and is an operation axis of the variable element 151 for 1Ala. Because of its
design inclination, it is attached with inclination in the inner carbon, while fixed to the variable
element 61 company Sueping, therefore, the operation knob μ) and the operation axis + 61 and
company round There is a position where the axis crosses [IC. In order to connect the operation
knob + 41 and the operation axis l, the present invention's present invention is constructed as
follows. That is, the main body (hereinafter referred to as the first main body) I7 to the operation
knob 141 is formed in a substantially birdcage shape, and is integrally fixed to the operation
knob 141 in advance via the connecting groove (40) t-. The main body 1'7) is a synthetic
(physically) strong synthetic resin such as acetal and As nylon etc., and is integrally provided by a
gold-made operation knob + 41 # c1jl. Incidentally, the main body +7) and the operation lever (4)
may be integrally formed of synthetic resin (as described above, FIG. 1 and FIG. 2 to FIG. 4). The
main body corresponding to the operation shaft 161K (hereinafter referred to as a second body)
