材が用いられる。As shown in FIG. 3, in the conventional fan sliding bearing, a bearing sleeve 40 that rotatably supports a fan drive shaft 3 integrated with a fan blade part 6 is a bearing formed on the fan main body lO side. It is fixed inside the storage case 2. The lubricating oil is supplied to these bearings through a pair of lubricating members 4 disposed at both ends of the bearing sleeve 400 (this lubricating member is often made of felt or the like impregnated with lubricating oil). In the figure, 7 is a fan drive circuit provided on the fan body 10 side, 5 is a shield member provided to prevent lubricating oil from leaking, and 9 is a drive shaft. 8 is a cover for the bearing portion. The shield member 5 is made of synthetic rubber or the like, and the drive shaft retaining member 9 is a fixing member having spring properties, such as a C-ring or an E-ring.
前記軸受スリーブ４０の内周面は、第３図に示すように

軸３と接触しない部分、つまり非接触部３０が形成され
ている。これはファン駆動軸３を有効的に支持するため
にとられた手段であって、こうすることによってファン
駆動軸３と軸受スリーブ４０との接触面積を最小限に抑
制しているわけである。As shown in FIG. 3, the inner circumferential surface of the bearing sleeve 40 has bearing surfaces 14 formed at both end portions thereof to come in loosely fitting contact with the fan drive shaft 3, and the fan drive shaft 3 at the center thereof. A non-contact portion 30 is formed. This is a measure taken to effectively support the fan drive shaft 3, and by doing so, the contact area between the fan drive shaft 3 and the bearing sleeve 40 is suppressed to a minimum.
しかしながら、従来の軸受スリーブ４０は、内周面に軸
受面１４と非接触部３０とを形成するための加工が必要

の加工方法は、■寸法精度の管理が難しい、■加工に特
殊な技術が必要であり、従って作業者が限定される。■
コスト高となる。■中央部分に潤滑油が供給され難い構
造であることから、いわゆる“軸受部の焼は付き現象”
を生じ易い、といった問題点がある。However, the conventional bearing sleeve 40 requires processing to form the bearing surface 14 and the non-contact portion 30 on the inner peripheral surface. This process can be carried out, for example, by pressing the bearing sleeve 40 in the axial direction using a press machine or the like to bulge the central portion outward, and then finishing the bearing surface 14 precisely using a reamer 5 or a drill. However, this processing method requires (1) difficult control of dimensional accuracy, (2) requires special techniques for processing, and therefore has a limited number of operators. ■
The cost will be high. ■Because the structure makes it difficult for lubricating oil to be supplied to the central part, the so-called "bearing seizure phenomenon" occurs.
There is a problem that it is easy to cause.
本発明はこのような従来の問題点を解決するためになさ

The arrangement shown in FIG. 2 is also much easier to process than the conventional one, and the lubricating oil is evenly supplied, making it possible to extend the life of the fan sliding bearing.
