112718号公報）が開示されている。(b) Background of the technology For example, in the case of control levers for air conditioners installed in automobiles, knobs are provided for the purpose of improving operability. With the exception of some levers that are entirely made of resin, the lever portion and the knob portion are constructed separately. Among these, the structure illustrated in FIG. 1 is generally adopted for those that connect the lever portion and the knob portion by insertion. That is, the tip insertion portion b of the lever a is inserted into the insertion hole d of the knob c, but at that time, the lever a is inserted between the tip insertion portion b and the insertion hole d.
A curved leaf spring e is interposed between the knob c and the knob c. Therefore, the knob c is connected to the lever a in a press-contact state. Recently, in order to make the joint stronger, as shown in FIG. and an actuating lever having a structure having concave and convex portions j provided on each of the lever f and the knob i (Utility Model No. 55-
112718) has been disclosed.

There was a drawback that it would come off if you pulled it hard in the length direction.

The slit h extends from the tip of the insertion part g to the second recess j
The two pieces that make up the insertion part g that face each other with the slit h in between are easy to bend, and when you grip this insertion part g with your fingers and apply more than a predetermined force to the lever part, they will face each other with the slit h in between. The two pieces easily come close to each other, and the concave and convex portions j provided on the knob i and the lever j tend to disengage, and when the knob i is strongly pulled in the length direction of the lever f, it comes off.

In this state, the resin lever is inserted into the resin knob, and the recesses or projections provided on both are engaged.
At the time of this insertion, before the recesses or projections provided on both sides are engaged, the warped wall is held in a state in which its width is slightly reduced by the recess, similar to the time of insertion, and We make it easy.

以下、この考案の実施例を第３図〜第６図に基

７図に示すように一方の側壁にのみ形成した場合
であつてもよい。 In the figure, reference numeral 1 denotes a knob, which is made of a nylon-based resin material that has excellent heat resistance, oil resistance, and desired hardness. This knob 1 has a head 2
An insertion hole (lever coupling portion) 3 having a rectangular opening 2' on the side is provided. Note that the opening 2' is necessary for mounting an indicator light (for example, an LED, etc.), and is not necessarily necessary for other purposes. The insertion coupling hole 3 is matched to the shape and dimensions of the tip insertion portion (knob coupling portion) 5 of the lever 4. At predetermined positions from the opening 2' (approximately at the center of both side walls), sawtooth protrusions 6 are integrally formed to engage the lever 4 in a manner that prevents it from slipping out. This convex portion 6 fits into a semicircular concave portion 7 provided on the lever 4 side. Note that the protrusion 6 may be formed only on one side wall as shown in FIG. 7.

ましい。 Like the knob 1, the lever 4 is made of a nylon resin material, and has an expansion coefficient equal to that of the knob 1. The distal end insertion portion 5 of the lever 4 is provided with a distorted wall 8 which is formed in a cross-sectional shape and is distorted in a direction perpendicular to the direction of insertion when the lever 4 is fitted into the knob 1. A thin wall portion 9 is provided in the central portion of the curved wall 8 and is formed in the direction of the plug-in connection structure. The thin wall portion 9 has a concave tip portion 10 and an inclined surface such that the wall thickness on the terminal end side is slightly increased, and the wall thickness is preferably 0.5 mm or less.
なお、前記歪曲壁８の両方の外先面の略中央部

よつて両者は強固に結合できる。 Incidentally, semicircular recesses 7 as described above are formed in the substantially central portions of both outer front surfaces of the distorted wall 8, so that the knob 1 can be attached upside down. With this structure, when the convex part 6 of the knob 1 and the concave part 7 of the lever 4 are connected, the distorted wall 8 easily slides on the gentle slope 11 of the convex part 66, and once When the convex part and the concave part fit together, the concave part 7 hangs on the steep slope 12 of the convex part 6, making it difficult to come off.In addition, the ratio of the applied force and the loosening force at this time is 2 kg or less, while the releasing force is 4 to 4 kg. A strength of 6Kg can be obtained. Therefore, when connecting the knob 1 and lever 4 by insertion, as shown in FIG. 6, when the knob 1 is inserted in the direction of arrow b, the tip insertion portion 5 of the lever
can be smoothly inserted into the insertion hole 3 of the knob 1 due to the distortion effect of the distortion wall 8, and after insertion, as shown in FIG. By the action and the engagement action between the recess 7 and the protrusion 6, the two can be firmly connected.

能となる。(g) Effects of the device As described above, this device has a resin knob with a recess or projection on the inner wall, and a projection or recess that engages with the recess or projection provided on the knob. In a lever-knob insertion structure consisting of a resin lever provided on the peripheral wall of the lever, the insertion part of the resin lever has a U-shaped cross section, and a recess is formed on the outer wall surface of the upright part. Or a thin wall having a convex portion, a concave portion on the tip side at the base connected to both the upright portions, and a thin portion that is distorted in a direction perpendicular to the insertion direction when the lever and knob are combined. and configured such that the recess provided on the tip side of the thin wall is located closer to the tip of the resin lever than the area where the recess or protrusion provided on the outer wall surface of the upright portion is located. Therefore, when connecting the resin knob and the resin lever, force is applied to the insertion part of the resin lever, causing the distortion of the distortion wall provided in the insertion part. The width of the concave part can be slightly reduced, making it easy to insert the knob. It is pressed against the inner wall of the knob, solidifies the engagement between the resin lever and the concave or convex portion provided on the knob, and makes it difficult to come off. For this reason, even if a force is applied to the knob, as in the case of a conventional lever-knob coupling structure using a slit, the distorted wall prevents the two upright walls from coming close to each other easily.
This eliminates the problem of the two easily disengaging and the knob coming off, making it possible to obtain high coupling reliability.
