本発明は、エンジンでベルト駆動される補機類
の支持装置に関し、詳しくは補機とエンジンとの
相対位置を変化させることによりベルトの張力を
調整できるようにした支持装置の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support device for auxiliary machinery that is belt-driven by an engine, and more specifically to a support device that allows belt tension to be adjusted by changing the relative position between the auxiliary machinery and the engine. Concerning improvements to equipment.
自動車用エンジンなどでは、例えばオルタネー

グポンプなどベルトを介してエンジン駆動される
補機類が多く設けられているが、これら補機類を
確実に駆動する一方でエンジンの負担を無用に増
やすことのないように、ベルトは常に適正な張力
に調整されていなければならない。 Automotive engines are equipped with many auxiliary devices that are driven by the engine via belts, such as alternators, air conditioner compressors, and power steering pumps. Belt tension must always be adjusted to the appropriate level to avoid unnecessary increases in belt tension.
このため、補機の支持装置またはエンジンに
は、必ずベルトの張力を調整する装置が設けられ
ているが、その一つに第１図に示したようなもの
がある。 For this reason, an auxiliary equipment support device or an engine is always provided with a device for adjusting belt tension, one of which is shown in FIG.
これは、補機（プーリ）１とエンジン本体２と

装置の一つであり、補機１を取り付けたブラケツ
ト４の一方の支点部４ａはエンジン本体２に直接
的に、他方の支点部４ｂはエンジン本体２に取り
付けた調整アーム５に各々結合されている。 This is a support device that allows the tension of the belt 3 to be adjusted by adjusting the relative position (distance between axes) between the auxiliary machine (pulley) 1 and the engine main body 2. One fulcrum part 4a of the bracket 4 to which the machine 1 is attached is directly connected to the engine body 2, and the other fulcrum part 4b is connected to an adjustment arm 5 attached to the engine body 2.

６，７にそれぞれ固定用のボルト８，９を介して
回動可能に支持され、他方の支点部４ｂはアーム
５に摺動可能に取り付けるようになつている。 One fulcrum portion 4a of the bracket 4 and the base end portion 5a of the arm 5 are rotatably supported by two support portions 6, 7 of the engine body 2 via fixing bolts 8, 9, respectively, and the other The fulcrum portion 4b of is adapted to be slidably attached to the arm 5.
アーム５には略長手方向に長孔１０が形成され

ーム５には、スライダ１２とネジ係合する細長い
ボルト状の調整ネジ１３が、軸方向の変位を拘束

る。 An elongated hole 10 is formed in the arm 5 in a substantially longitudinal direction, and a connecting pin (bolt) 11 passing through the elongated hole 10 is formed in the fulcrum portion 4b of the bracket 4.
A slider 12 that slides along the long hole 10 together with the pin 11 is provided. Furthermore, an adjustment screw 13 in the form of a long and thin bolt, which is threadedly engaged with the slider 12, is supported by the arm 5 along the elongated hole 10, with displacement in the axial direction being restrained.
この装置では、各ボルト８，９，１１を緩めた

動するのに伴つて、支持部７を中心としてブラケ
ツト４および補機１が回動する。これによりベル
ト３の張力が調整されるのであり、従つて、簡単
な操作で正確な張り調整ができるわけである。 In this device, when the adjusting screw 13 is turned with each bolt 8, 9, 11 loosened, the bracket 4 and the auxiliary machine 1 rotate around the support part 7 as the slider 12 slides. . This allows the tension of the belt 3 to be adjusted, and therefore the tension can be adjusted accurately with a simple operation.
しかしその反面、このような装置によると、調
整ネジ１３が長孔１０の側方に位置し、スライダ

曲げモーメントが働き、これによつて調整ネジ１
３が曲げ作用をうけて、その耐久性を損つたり、
著しくは破損するおそれがあつた（第２図参
照）。 However, on the other hand, according to such a device, the adjustment screw 13 is located on the side of the elongated hole 10 and is offset from the connecting pin 11 of the slider 12, so the slider 12 cannot be moved by turning the adjustment screw 13. When adjusting the adjustment screw 1, a bending moment acts on the slider 12 due to the tension of the belt 3.
3 is subjected to bending action and its durability is lost,
There was a serious risk of damage (see Figure 2).
また、調整ネジの中心と、長孔の中心軸方向と
が、オフセツトしないものとして、例えば特公昭
40−28963号に示されるようなものがあるが、本
発明の様な補機の支持装置では、そのレイアウト
上の問題や強度上の問題で、どうしてもオフセツ
トせざるを得ない場合がある。 In addition, as a case where the center of the adjustment screw and the central axis direction of the elongated hole are not offset, for example,
No. 40-28963 discloses a support device for auxiliary equipment such as the one of the present invention, but there are cases where offset is unavoidable due to layout problems and strength problems.
本発明はこのような問題点に着目してなされた
もので、スライダをアームの長手方向に案内する
ガイド部を形成して、連結ピンを中心としたスラ
イダの回動を拘束することにより上記問題点を解
消することを目的とする。 The present invention has been made in view of these problems, and it solves the above problems by forming a guide portion that guides the slider in the longitudinal direction of the arm and restraining the slider from rotating around the connecting pin. The purpose is to eliminate the points.
以下、本発明を図面に示した実施例に基づいて
説明する。 Hereinafter, the present invention will be explained based on embodiments shown in the drawings.
本発明では、第３図Ａ，Ｂに示したように、ア
ーム５とスライダ１２との間に、スライダ１２を

１０と平行な平滑面に形成するとともに、このア
ーム側部５ｂ，５ｃと摺接するガイド壁部２１を
スライダ１２に形成する。 In the present invention, as shown in FIGS. 3A and 3B, a guide part 20 is formed between the arm 5 and the slider 12 for guiding the slider 12 along the elongated hole 10. The portions 5b and 5c are formed as smooth surfaces parallel to the elongated hole 10, and the slider 12 is provided with a guide wall portion 21 that comes into sliding contact with the arm side portions 5b and 5c.
こうすることにより、スライダ１２はほぼピン
１１を中心とした回動が拘束された状態で長孔１
０に沿つて摺動するので、ベルト張力の調整時に
調整ネジ１３が曲げをうけるようなことがなく、
従つて調整ネジ１３の耐久性が損われることがな

擦が低減するため操作力も軽くできる。 By doing this, the slider 12 moves through the elongated hole 1 while its rotation about the pin 11 is almost restricted.
0, the adjustment screw 13 will not be bent when adjusting the belt tension.
Therefore, the durability of the adjusting screw 13 is not impaired, and furthermore, since the friction at the threaded engagement portion with the slider 12 is reduced, the operating force can be reduced.
また、本発明では連結ピン１１と調整ネジ１３

Since the axes of the connecting pins 11 are separated by a predetermined distance, there is no need to increase the diameter of the connecting pin 11 or make it into a special shape due to strength requirements, and in other words, standard bolts can be used as the connecting pins 11. can. Furthermore, in conjunction with this, the guide portion 20 of the slider 12 is secured to the necessary length, and the arm 5 is
Since a sufficient sliding contact area can be secured between the arm 5 and the arm 5, the strength burden on the arm 5 can be reduced or the weight thereof can be reduced accordingly.
