される。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. First, a first casing 1 is made of metal and has an opening and a closing part. Inside this first casing 1, there is a variable resistor 2 having an operating shaft 2a and other electronic components ( A printed circuit board 3 (not shown) mounted thereon is inserted such that the electronic component side thereof is located on the closed side of the first casing 1, and the resin-made printed circuit board 3 is inserted to close the opening of the first casing 1. The printed circuit board 3 is also fixed in a socket-shaped second casing 4. The second casing 4 has a plurality of arm parts 4a at its tip that presses at least the end of the printed circuit board 3 on the opening side of the first casing 1 at two or more places, and the arm parts 4a has an elastic part in the shape of a semicircle with a thin wall at the tip A and A', and this elastic part mechanically connects the second casing 4 to the first casing 1. This allows the printed circuit board 3 to be fixed without wobbling even when force is applied to the operating shaft 2a. In this case, if the design value of the pressing force of the above A and A' parts is made slightly larger, even if the variation in dimensions of each part becomes large, it will be possible to sufficiently compensate for it, and the operating shaft 2a will be The printed circuit board 3 is fixed while preventing waviness. Here, printed circuit board 3
The fixation of the closed portion side of the first casing 1 is performed by a part of the variable resistor 2 coming into contact with the closed portion of the first casing 1; This may also be done by providing a locking protrusion on a part of the side wall. Furthermore, a protrusion 1a is provided on the side wall of the opening side of the first casing 1 to prevent the second casing 4 from coming off. An insertion hole 1b is formed through which the shaft 2a is inserted. Further, 5 is another printed circuit board fixed between the stepped portion 4c of the arm portion 4a of the second housing 4 and the bottom of the socket portion 4b, and this printed circuit board 5 also includes electronic components (not shown). ), and both printed circuit boards 3 and 5 are electrically connected to each other by lead wires (not shown) or the like. 2nd above
Appropriate parts are attached to the socket portion 4b of the casing 4.
