とにある。2. Description of the Related Art An example of a seesaw type switch having a conventional illumination is shown in FIG. The box-shaped switch case 1 is attached to a member 2, and a light source 3 for illumination is arranged inside thereof. Material 2 for switch case
A knob mounting portion 4 that is a passage for guiding light inside is provided integrally with the surface facing the. Rotating shafts 5 project from both opposite sides of the knob mounting portion 4 and are integrally formed concentrically. The knob 6 has a fitting portion 7 which is fitted into the knob mounting portion 4, and a shaft hole 6a of the rotary shaft 5 of the knob mounting portion is formed on a side portion forming the fitting portion 7. And knob 6
When is attached to the knob mounting portion 4, the rotary shaft 5 is fitted into the shaft hole 6a, and the knob 6 is swingably supported by the knob mounting portion.
When the knob is operated, the switch arranged in the switch case operates according to the swing of the knob. Further, an index for transmitting light is provided on the surface on the side where the knob 6 is pressed, and the illumination light from the light source 3 passes through the index and is emitted to the outside so that the index can be visually recognized. Since the switch case 1 is manufactured by the mold integral molding, when the rotary shaft 5 is provided on the outer side of the knob mounting portion 4, this portion must be molded by the movable mold from the inside of the switch case. Therefore, a hole for removing the mold is formed on the knob mounting portion side of the switch case during molding. Since the illumination light of the knob leaks to the outside through the hole, the hole is blocked by another component to prevent the light from leaking. As a result, the number of parts and the number of assembling steps increase, and the structure becomes complicated. An object of the present invention is to provide a seesaw type switch which can be easily molded and has a simple structure to prevent light leakage.

部からの洩光防止効果が高められる。In order to achieve the above object, the invention according to claim 1 provides a switch case in which a knob mounting portion for mounting a knob for operating a switch is projected and integrally molded, and a light source is arranged inside. A seesaw type switch provided with a rotary shaft projecting to the side of the knob mounting part and having a hole formed through the switch case at the time of molding the rotary shaft on the surface on the knob mounting part side. The wall portion is located at the hole and extends near the rotation axis. According to a second aspect of the present invention, in the first aspect of the invention, a knob receiving surface is formed on the rotation shaft side of the wall portion, a hole is opened in the knob receiving surface, and the hole is formed on the side portion of the knob. The structure is such that an opposing surface for closing the above is formed. Claim 3
In the invention of claim 2, the knob receiving surface of the wall portion has a concave cylindrical surface shape, and a convex cylindrical facing surface matching the knob receiving surface is formed on the knob side. According to the structure of claim 1, the hole of the switch case is provided in the wall extending to the vicinity of the rotation axis of the knob, and the illumination light of the knob is blocked by the wall. Claim 2
According to the configuration, by arranging the facing surface on the knob side on the knob receiving surface formed on the rotary shaft side of the wall portion, the hole opened in the knob receiving surface is closed by the facing surface, and the hole portion is opened. Leakage from light is prevented. According to the structure of claim 3,
By matching the facing surface with the entire knob receiving surface, the effect of preventing light leakage from the hole is enhanced.

In each figure, parts corresponding to the conventional parts shown in FIG. 5 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. A wall portion 11 is formed on the outside of the surface of the knob mounting portion 4 on which the rotary shaft 5 is provided, and the wall portion 11 is formed.
On the rotary shaft 5 side, a concave semicircular knob receiving surface 11a centering on the rotary shaft 5 is formed. On the other hand, a convex semicircular light shielding portion 12 centering on the shaft hole 6a is integrally provided on the switch case side of the surface of the knob 6 facing the shaft hole 6a. The outer periphery of the light shielding portion 12 is a facing surface 12a that matches the knob receiving surface 11a formed on the wall portion 11. In addition, the hole 1a of the switch case 1 has a wall 11
Is opened on the knob receiving surface 11a. Since the knob receiving surface and the facing surface on the knob side are close to or in contact with the knob mounting portion, the hole is closed by the facing surface even when the knob swings. Therefore, since the hole provided when the switch case and the rotary shaft of the knob are integrally molded is closed by the light-shielding portion of the knob when the knob is assembled to the switch case, the light emitted from the light source passes through the hole and is exposed to the outside. Can be prevented from leaking.
