Description

本発明は、自動車におけるダイナモ（発電機）又はコンプレッサ（エアコンディショナーのコンプレッサ）用のベルト張力調整装置に関するものである。   The present invention relates to a belt tension adjusting device for a dynamo (generator) or a compressor (compressor of an air conditioner) in an automobile.

自動車におけるダイナモ又はコンプレッサは、そのベルトの張力を調節する方向に円弧状の案内ブラケットに沿って回動し得るようにエンジンルーム内に枢着されている。このダイナモ又はコンプレッサのベルトの張力を調節する際には、一般にダイナモ又はコンプレッサとエンジン等との間の狭い隙間にこじ棒を挿入して該こじ棒をこじることによりダイナモ又はコンプレッサを回動させるという手法が採られている。   A dynamo or compressor in an automobile is pivotally mounted in an engine room so that it can be rotated along an arcuate guide bracket in a direction to adjust the tension of the belt. When adjusting the tension of this dynamo or compressor belt, it is generally said that a dynamo or compressor is rotated by inserting a koji bar into a narrow gap between the dynamo or compressor and the engine, etc. The technique is taken.

しかるに、上記従来の手法においては、ダイナモ又はコンプレッサとエンジン等との間の隙間は非常に狭いため、この隙間にこじ棒を挿入してこじるとうい作業は極めて困難である。また、この作業中にこじ棒がエンジンルーム内のプラスチック部品等に当接して該部品を損傷させるおそれもある。   However, in the above conventional method, the gap between the dynamo or the compressor and the engine or the like is very narrow, so that it is extremely difficult to perform the operation by inserting a pry bar into this gap. In addition, there is a possibility that the bar will come into contact with a plastic part or the like in the engine room during this operation and damage the part.

本発明はこのような問題を解決し、ダイナモ又はコンプレッサのベルトの張力を容易に且つプラスチック部品等を損傷することなく調整し得るようにしようとしてなされたものである。 The present invention has been made to solve such problems and to make it possible to easily adjust the tension of a dynamo or compressor belt without damaging plastic parts or the like.

上記課題を解決するために、本発明は下記の自動車におけるダイナモ又はコンプレッサ用のベルト張力調整装置を提供するものである。   In order to solve the above-mentioned problems, the present invention provides a belt tension adjusting device for a dynamo or a compressor in an automobile described below.

[Invention of Claim 1]
When the belt tension adjusting device according to claim 1 is used, the substantially arcuate fitting portion of the rotating shaft is brought into contact with one end of the arcuate guide groove, and the arcuate fitting portion is brought into contact with the one end of the guide groove. In this state, it is fitted and the side surface of the substantially cylindrical body is brought into contact with the dynamo or the compressor. In this state, a wrench (spanner) is engaged with the substantially cylindrical wrench engaging means, and the substantially cylindrical body is rotated by the wrench. See Figure 4. In this case, the substantially columnar body rotates about a rotation shaft projecting at an eccentric position in the substantially columnar body. At this time, since the arcuate fitting portion of the rotating shaft is in contact with one end of the guide groove and the side surface of the substantially cylindrical body is in contact with the dynamo or the compressor, the arcuate fitting portion of the rotating shaft is in the guide groove. Cannot advance or retreat within. Therefore, when the substantially cylindrical body is rotated about the rotation axis at the eccentric position, the dynamo or the compressor is rotated along the guide groove with the pivot axis as the rotation center. As a result, the tension of the dynamo or compressor belt is adjusted.
