この発明は前記のファンの取付構造に関するものである
。The present invention relates to a mounting structure for the above-mentioned fan.
従来の取付構造は、ファンボスを回転軸にネジ込むか、
回転軸に平坦部を設け、これに、ファンボスに直角に螺
合したネジの先端を圧接してファンを固定するものであ
った。The conventional mounting structure is to screw the fan boss onto the rotating shaft, or
A flat part was provided on the rotating shaft, and the fan was fixed by pressing the tip of a screw screwed into the fan boss at right angles to the flat part.
しかし、前者はネジ込みの際に回転軸を回らないように
固定しなけれはならないから作業の段取りが面倒である
のみならず、ネジ込みは取付け。However, with the former, the rotating shaft must be fixed so that it does not rotate when screwed in, which not only makes the work setup troublesome, but also screws in the installation.
取外しのいずれかがゆるみ勝手になるから、伺らかの手
段で回り止めを施さなければならない。後者は前者の欠
点がない代りにネジ部品が増すとともに回転軸に直角の
方向にネジ全回定する作業に難点がある。Since one of the parts that can be removed will become loose, you will have to use some other means to stop it from rotating. Although the latter does not have the disadvantages of the former, it has an increased number of threaded parts and has difficulties in fully rotating the screw in a direction perpendicular to the axis of rotation.
この発明の目的は、上記の両者の欠点を解消し、ファン
の取付け、取外し作業が簡単な構造を提供することであ
る。An object of the present invention is to eliminate both of the above-mentioned drawbacks and to provide a structure that allows easy installation and removal of the fan.
この発明の構成は特許請求の範囲の項に記載した通りで
あるが、次に図面に示した実施例によって、本発明の構
成とともにその作用効果を説明する。Although the structure of the present invention is as described in the claims, the structure of the present invention and its effects will be explained below with reference to embodiments shown in the drawings.

２１に係合する突起１Ｂが設けられる。According to the present invention, the rear end of the rotating shaft 3 is provided with the figures 3 and 4.
As shown in the figure, an engagement groove 22 that is perpendicular to the axis is formed in a part of the circumferential surface, and a notch having a flat part 21 that is parallel to the axis is provided on the end surface of the axis. On the other hand, in the cylindrical portion of the fan boss 12 that is fitted to the shaft end, a cantilever-shaped operator 17 is formed by two cuts parallel to the shaft, and this operator [is connected to the aforementioned engagement groove 22]. A claw 16 is provided to be inserted into. Further, the bottom surface of the boss 12 is provided with a protrusion 1B that engages with the above-mentioned cutout plane portion 21.
ファン１０の軸３への取付けは次のように行われる。The fan 10 is attached to the shaft 3 as follows.
軸３の端部にファンボス１２を合わせ、矢印の方向にス

起２３を乗り越え、溝２２内に落ち込んで溝と係合する
。これと同時に、ファンボスの底部の突起１８が軸端の
切欠の平面部２１と係合する。When the fan boss 12 is aligned with the end of the shaft 3 and slid in the direction of the arrow, the pawl 6 rides over the protrusion 23 between the notch 21 and the groove 22, falls into the groove 22, and engages with the groove. At the same time, the protrusion 18 on the bottom of the fan boss engages with the flat part 21 of the notch at the end of the shaft.
爪６と溝２２の係合はファンの抜は止めとなり、突起１
８と平面部２１との係合はファンの回り止めとなる。The engagement between the pawl 6 and the groove 22 prevents the fan from being removed, and the protrusion 1
The engagement between the fan 8 and the flat portion 21 prevents the fan from rotating.
ファッ１０′ｆｔ軸３から外す場合は、操作子１７の先
端を引き上けながらファンを手前に引けばよい。To remove the fan from the 10'ft shaft 3, pull the fan toward you while pulling up the tip of the operator 17.
本発明によるファン取付構造は、軸における溝２２と切
欠平面部２１を同時に一工程で加工できるから製作が容
易である。The fan mounting structure according to the present invention is easy to manufacture because the groove 22 and the cutout plane portion 21 in the shaft can be simultaneously processed in one step.
切欠の位置は第５図のように中央に設けても、第６図の
ように、溝２２と反対の側に設けても同効である。The same effect can be obtained whether the notch is located in the center as shown in FIG. 5 or on the side opposite to the groove 22 as shown in FIG.
本発明によれば、次の効果がある。According to the present invention, there are the following effects.
（１）冷却ファンを、工具を使わないで、回転軸にワン
タッチで取付け、取外すことができる。(1) The cooling fan can be installed and removed from the rotating shaft with one touch without using any tools.
（２）ネジなどの部品？用いないで、抜は止め、回り止
めができる取付構造となすことができる。(2) Parts such as screws? It is possible to create a mounting structure that prevents removal and rotation even when not in use.
