、内側操作軸（４）に対するつまみの図示は省略した。FIG. 1 is an explanatory diagram of the structure of the conventional underside knob attachment. In this figure, (1) is an audio equipment set, and a hollow outer operating shaft (3) made of gold plate is attached to a bearing (2) protruding from the set (1). The inner operating shafts (4) are rotatably fitted to the supports 3a).
is formed. (5) is a knob made of resin, and has a shaft fitting hole (5a) for fitting onto the outer operating shaft (3), and the shaft fitting hole (5a) is provided with the locking recess (5a). A locking convex portion (5b) that fits into 3a) is integrally formed. Note that illustration of the knob for the inner operating shaft (4) is omitted.

By fitting into the recess (3a), the knob (5) is stopped from rotating relative to the outer operating shaft (3) and positioned in the direction of the arrow.

など、結果として高価となる欠点があった。In the above configuration, the outer operating shaft (3) is finished straight by cutting, and the fitting dimensions of the knob (5) are strictly controlled. However, if the outer operating shaft (3) is finished by cutting, the accuracy similar to that of a mold can be achieved, the machining error 1t' fluctuation is large, and the dimensional run of the knob molding mold becomes difficult. However, there were disadvantages in that the molding die had to be changed and the knob (5) and the outer operating shaft (3) had to be matched in actuality, resulting in high costs.

まう欠点があった。On the other hand, if the knob (5) is not tightly fitted to the outer operating shaft (3) K, as shown in Figure 2,
) was used to fit a tightening fitting (spring) (6) onto the boss (5c) to reduce the fitting dimension of the knob (5).
As mentioned above, no matter how strict the fitting dimensions of the knob (5) are fitted to the straight outer operating shaft (3), if you pull it with more than a certain amount of force, the knob (5) will come off. There were drawbacks.

〔発明の実施例〕
以下、この発明の実施例を図面にもとづいて説明する。This invention was made to eliminate the above drawbacks.
A claw is provided in the shaft fitting hole of the knob, and a claw 114 is provided on the outer periphery of the operating shaft, and when the knob is fitted to the operating shaft in the shaft fitting hole, the mold is fitted and locked in the groove. By configuring it to do so, the knob can be attached to the operating shaft inexpensively and firmly. Embodiments of the Invention Below, embodiments of the present invention will be described based on the drawings.

The claw (5d) of the knob (5) is pressed and deformed by the outer circumferential surface of the outer operating shaft (3) and is fitted onto the outer operating shaft (3) in the direction of arrow A. ), and as shown in FIG. 4, the groove (3b) K is fitted and locked. Thereby, the knob (5) is positioned and fixed in the axial direction with respect to the outer operating shaft (3).

By fitting into the locking recess (3a) of 3), rotation of the knob (5) with respect to the outer operating shaft (3)K is also prevented. Note that the above mold (5d) may be provided in an annular manner around the axis of the knob (5), or may be provided partially, but this may be arbitrarily adopted depending on the form of the claw (5d). .

点からも安価なものとすることができる。As described above, according to the present invention, the knob is coupled to the operating shaft in the axial direction to maintain engagement between the claw and the groove, so that it does not easily come off. That is, the knob can be firmly attached to the operating shaft without requiring any accessories such as fastening fittings, and is therefore inexpensive. In addition, by firmly attaching the knob to the operating shaft in this way, the knob can fully exhibit its effect as a button-pull type in the operating shaft, such as the volume shaft of an audio device, for example. Furthermore, one groove is formed in each of the above-mentioned mold clamps on the operating shaft, but with a structure in which the claws and grooves are engaged, the fitting tolerance between the knob and the operating shaft is relaxed, which improves workability and dimensional control. It can also be made inexpensive.
