本発明は、例えば自動二輪車用のエンジンにおいて、そ
のシリンダヘッドにヘッドカバーを締付は固定する装置
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a device for tightening and fixing a head cover to a cylinder head of, for example, a motorcycle engine.
エンジンの軽」化対策の一つとして、従来、シリンダヘ
ッドに被嵌されるヘッドカバーを、合成樹脂製としたも
のが知られている。BACKGROUND ART Conventionally, as one measure to reduce the weight of an engine, a head cover that is fitted over a cylinder head is made of synthetic resin.
このヘッドカバーをシリンダヘッドに締付ける手段とし
て、従来、第７図に示すように、シリンダヘッド１に被
せられるヘッドカバー２の上面２ａに、複数のボルト挿
通孔３を設け、このボルト挿通孔３に挿通したボルト４
をシリンダヘッド１側にねじ込むことで、ヘッドカバー
２の周壁部２ｂをシリンダヘッド１に重ね合わせて締付
は固定する、いわゆるセンタボルト方式がある。Conventionally, as a means for tightening this head cover to the cylinder head, as shown in FIG. bolt 4
There is a so-called center bolt method in which the circumferential wall portion 2b of the head cover 2 is superimposed on the cylinder head 1 by screwing it into the cylinder head 1 side, and is tightened and fixed.
このセンタボルト方式では、シリンダヘッド１とヘッド
カバー２との合面間にガスケット５を介在させ、上記ボ
ルト４を締付けた際に、上記白面間でガスケット５を挾
み込んで所定の面圧をかけることにより、この白面をシ
ールしている。In this center bolt method, a gasket 5 is interposed between the mating surfaces of the cylinder head 1 and the head cover 2, and when the bolt 4 is tightened, the gasket 5 is inserted between the white surfaces to apply a predetermined surface pressure. By doing so, this white surface is sealed.
ところが、この従来構成では、ヘッドカバー２の周壁部
２ｂには、常にボルト４の締付けに伴う圧縮力が加わる
ため、エンジン運転中、ヘッドカバー２が高温となると
、このヘッドカバー２を合成樹脂製としたことによる剛
性不足により、ヘッドカバー２の周壁部２ｂが、第７図
中想像線で示すように、側方に張出すように変形してし
まうことがあった。However, in this conventional configuration, compressive force is constantly applied to the peripheral wall portion 2b of the head cover 2 due to the tightening of the bolts 4, so when the head cover 2 becomes hot during engine operation, the head cover 2 is made of synthetic resin. Due to the lack of rigidity, the peripheral wall portion 2b of the head cover 2 sometimes deforms so as to bulge out to the side, as shown by the imaginary line in FIG.
このため、ガスケット５に加わる面圧が低下して、シー
ルが不完全となったり、ヘッドカバー２の熱変形が大き
くなると、ガスケット５が白面から外れて、シール性が
損われてしまうことがあり、ヘッドカバー２の白面部分
からオイル漏れが発生する等の不具合があった。For this reason, if the surface pressure applied to the gasket 5 decreases, resulting in an incomplete seal, or if the thermal deformation of the head cover 2 increases, the gasket 5 may come off the white surface and the sealing performance may be impaired. There were problems such as oil leaking from the white part of the head cover 2.
そこで、本発明においては、互いに突合わされるヘッド
カバーの周壁部と被カバー体の突合わせ壁部の白面のい
ずれか一方の周縁部に、他方の白面の周縁部に係止され
て、上記周壁部を突合わせ壁部に対して位置決め保持す
るストッパ壁を形成したことを特徴とする。Therefore, in the present invention, the peripheral wall of one of the white surfaces of the abutting wall of the head cover and the abutting wall of the covered body is locked to the peripheral edge of the other white surface. It is characterized in that a stopper wall is formed for positioning and holding the butt against the abutting wall.
この構成によれば、カバーが高温となった際、その周壁
部がボルトの締付は力に屈して外側に張出すように変形
しようとしても、この変形に伴う周壁部の変位は、スト
ッパ壁によって阻止されることになり、これら周壁部と
突合わせ壁部との白面のずれを未然に防止することがで
きる。According to this configuration, when the cover becomes hot, even if the peripheral wall part of the cover succumbs to the tightening force of the bolt and tries to deform so as to bulge outward, the displacement of the peripheral wall part due to this deformation will be prevented by the stopper wall. Therefore, it is possible to prevent the white surfaces of the peripheral wall portion and the abutting wall portion from shifting.
このため、カバーの白面からガスケットが外れたり、こ
のガスケットに加わる面圧が低下することもなく、カバ
ーの剛性不足に伴うシール性能の低下を解消することが
できる。Therefore, the gasket does not come off from the white surface of the cover, and the surface pressure applied to the gasket does not decrease, making it possible to solve the problem of deterioration in sealing performance due to insufficient rigidity of the cover.
以下本発明の第１実施例を、第１図ないし第５図にもと

−ツバ壁３１の内側面にまで達している。By the way, on the inner peripheral edge of the mating surface 22a of the peripheral wall portion 22, there are a plurality of stopper walls 3 that protrude from the mating surface 22a.
1... are integrally formed. As shown in FIG. 3 and FIG.
7 and are provided with an interval between them, respectively, and the surrounding wall portions 22
It is continuous with a flesh floating part 32 protruding from the inner surface of the body. These stopper walls 31 abut the peripheral wall portion 22 against the wall portion 1.
6, when stacked on the abutting wall 16, it enters the inside of the abutting wall 16 and is locked to the inner peripheral edge of the mating surface IGa, positioning and holding the peripheral wall 22 with respect to the abutting wall 16. In addition, on the inner peripheral surface of the cam cover part 18.18,
A reinforcing rib 33 is provided in a protruding manner, and a part of this rib 33 passes over the thick part 32 on the inner surface of the peripheral wall part 22 and is inserted into the slot.
- It reaches the inner surface of the collar wall 31.

維持することができる。According to such a configuration, the peripheral wall portion 2 of the head cover 17
2 is provided with a stopper wall 31 that is locked to the inner peripheral edge of the butt wall 1G, so that when the head cover 17 becomes hot, the peripheral wall 22 prevents the bolts 29 from being tightened by force. Even if the circumferential wall portion 22 tries to deform by bending to the outside and bulges outward, the deformation of the peripheral wall portion 22 is prevented by the engagement between the stopper walls 31 . . . and the abutment wall portion 16. Therefore, the mating surface 22a between the peripheral wall portion 22 and the abutting wall portion 16
, 16a does not shift, and these mating surfaces 16a
, 22a and the gasket 24 can be maintained in good contact at all times.
したがって、ガスケット２４が突合わせ壁部１６の合面
１６ａから外れたり、ガスケット２４に加わる面圧が低
下することもなく、ヘッドカバー１７の剛性不足に起因
するシール性能の低下を確実に防止することができる。Therefore, the gasket 24 does not come off the mating surface 16a of the butt wall portion 16, and the surface pressure applied to the gasket 24 does not decrease, thereby reliably preventing the sealing performance from deteriorating due to insufficient rigidity of the head cover 17. can.
