【考案の詳細な説明】本考案は、複数個、近接配置された押釦部を有
する押釦機構に関するものであり、特に、押釦部
間の間隔を極めて接近させることを可能としたも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a push button mechanism having a plurality of push button parts arranged close to each other, and in particular, it is possible to make the distance between the push button parts extremely close.

ところで、最近に於いては、押釦部２′と押釦部
２′の間隔Ｔが0.5〜1.0mm位のものが要求されて
きているが、斯かる極めて接近した押釦部を一体
成型することは、金型作成の面で、非常に困難で
あつた。 For example, in a car radio that allows preset channel selection, the intervals between the plurality of preset buttons are extremely close. FIG. 1 shows a plan view of a conventional push button mechanism 1, in which a plurality of push button parts 2', 2'...
are integrally connected at a connecting portion 3, and are integrally molded from synthetic resin (see Fig. 1).
By the way, recently there has been a demand for a space T between the push button parts 2' of about 0.5 to 1.0 mm, but it is difficult to integrally mold such push button parts that are very close together. It was extremely difficult to create the mold.

そこで、本考案は、相対向する押釦部の側面を
蛇行面とし、斯かる押釦部に直線状の稜線部を有
するキヤツプをかぶせる構成としたものである。
以下、図面に示す実施例を参照して詳述する。 Therefore, in the present invention, the side surfaces of the opposing push button sections are formed into meandering surfaces, and the push button sections are covered with a cap having a linear ridgeline section.
Hereinafter, a detailed description will be given with reference to embodiments shown in the drawings.

ている。 FIG. 2 shows a plan view of the push button mechanism 1 according to the present invention, and the opposing side surface 2a of the push button portion 2 is a meandering surface. Then, the push button portion 2 is covered with the cap 5 (see FIG. 4). and,
The side surface (inner surface) of the cap 5 is a straight plane that contacts the topmost portion 2a' of the meandering surface 2a of the push button portion 2. That is, the ridgeline on the side surface of the cap 5 is a straight line.

それ故、押釦部２の蛇行面２ａの間隔Ｔはある
程度広くとることができ、金型作成上の困難が解
消されると共に、キヤツプ５をかぶせることによ
り、キヤツプ５同志の間隔ｔは十分小さくするこ
とができる。 Therefore, the interval T between the meandering surfaces 2a of the push button part 2 can be made wide to some extent, which eliminates the difficulty in making a mold, and by covering the caps 5, the interval t between the caps 5 can be made sufficiently small. be able to.

ノイズの発生を防止することもできる。 Note that if the flange 2b is provided that slightly protrudes from the top 2a' of the meandering surface 2a of the push button part 2, when the cap 5 is made of a conductive material, the side surfaces of the cap 5 will not touch each other and will be conductive. Since the side surface of the sexual cap 5 and the synthetic resin flange 2b come into contact with each other, it is also possible to prevent the generation of electrical noise.

As shown in the side view of the figure, the right end of the connecting part 3 is supported in the figure, and the push switch 6 is operated by a protruding piece 4 provided at the lower part of the push button part 2.

Claims

[Scope of utility model registration request]

It consists of a plurality of push button parts, a connecting part for connecting these push button parts in parallel at a predetermined interval, and a cap that is placed over the push button parts, and the opposing side surfaces of the push button parts are formed in a meandering shape. The push button mechanism is characterized in that the opposing side surfaces of the cap are straight planes that touch the top of the meandering surface of the push button part.
