バーの提供を目的とするものである。[Detailed description of the invention] This invention relates to a sound insulation cover for an internal combustion engine that improves the installation of the sound insulation cover body and the inspection cover that covers the opening of the body, and when the inspection cover is removed. It is an object of the present invention to provide a sound insulating cover that has no protrusions that may obstruct inspection work and has good sealing properties between the inspection cover and the cover body.
以下この考案の一実施例につき図を参照して説明する。An embodiment of this invention will be described below with reference to the drawings.
図において、１は内燃機関（図示せず）の上面部を除く
全体を包囲する遮音カバ一本体で、上面開口部の周縁に

ａ下方にはナツト３がフランジ２に固着されたホルダ４
によって定着されている。In the figure, reference numeral 1 denotes a sound insulating cover body that surrounds the entire internal combustion engine (not shown) except for the top surface, and a flange 2 is formed on the periphery of the top opening.
Below a is a holder 4 with a nut 3 fixed to the flange 2.
It is established by

いる。5 is an inspection cover that covers the opening of the cover main body 1;
The outer peripheral portion 5a of this cover 5 has a semicircular cross section and bulges downward.
A rubber latch elastic sealing material 6 interposed between the cover body 1 and the flange 2 is attached to the cover body 1, and the large diameter part is engaged with the outer wall of the outer peripheral part 5a of the cover 5, and the small diameter part is covered. A cylindrical spacer 7 is inserted through the spacer 5 and the sealing material 6.
前記スペーサ７を上方から貫通させて締付ボルト８を前
記ナツト３に締付けることにより、シール材６を弾性変
形させて点検用カバー５か勿バ一本体１に締付けられる
。By passing the spacer 7 from above and tightening the tightening bolt 8 to the nut 3, the sealing material 6 is elastically deformed and is tightened to the inspection cover 5 or the cover body 1.
上記弾性シール材６は内燃機関をシールするもので、上
記カバー５の外周部５ａとカバ一本体１のフランジ２と
の間にカバー５の全外周を覆うように介在されて上記カ
バー５の外周部５ａに固着されるものである。The elastic sealing material 6 seals the internal combustion engine, and is interposed between the outer periphery 5a of the cover 5 and the flange 2 of the cover main body 1 so as to cover the entire outer periphery of the cover 5. It is fixed to the portion 5a.
以上のように構成した遮音カバーは、内燃機関の整備９
点検等に前記ボルト８を外すことにより、点検用カバー
５が取外されると共に、シール材６およびスペーサ７も
フランジ２上から撤去され、従ってカバ一本体１の開口
周縁部上には突起物がなくなる。The sound insulating cover configured as described above is suitable for internal combustion engine maintenance 9.
By removing the bolts 8 for inspection, etc., the inspection cover 5 is removed, and the sealing material 6 and spacer 7 are also removed from the flange 2, so that no protrusions are left on the opening periphery of the cover body 1. disappears.
また点検用カバー５の取付時にはボルト８の頭部とフラ
ンジ２でスペーサ７が挟持されることにより、シール材
６の弾性変形がほぼ一定量に規制される。Further, when the inspection cover 5 is attached, the spacer 7 is held between the head of the bolt 8 and the flange 2, so that the elastic deformation of the sealing material 6 is regulated to a substantially constant amount.
なお、この実施例において、スペーサ７の頭部の点検用
カバー外周部５ａに当接される部分は、この部分と密接
される円弧状に形成されている。In this embodiment, the portion of the head of the spacer 7 that comes into contact with the inspection cover outer peripheral portion 5a is formed into an arc shape that is in close contact with this portion.
また、前記カバー外周部５ａを円弧状にすることは、厚
さが薄いカバー５を補強するものである。Furthermore, forming the cover outer circumferential portion 5a into an arc shape serves to reinforce the thin cover 5.

本体１と脚部５ａ。Further, the elastic sealing material 6 of this embodiment includes a pair of leg portions 6 a and 6 b whose distal ends are curved inward on opposing surfaces, and a link formed between these leg portions 6 a and 6 b. The outer periphery is integrally connected by the attachment part 6C, and a semicircular surface 6f along the outer periphery of the inspection cover 5 is formed by the connection part 6C and the holding parts 6d and 6e extending above the attachment part 6C. 5a, and improves the adhesion between the sound insulating cover body 1 and the leg portions 5a.
６ｂが内外２重に圧接してシールを確実にし、さらに脚
部６ａ、６ｂの締付けに当って圧縮ではなく撓曲で変形
するために小さい締付力ですむようにしである。6b is pressed into contact with the inside and outside twice to ensure a secure seal, and furthermore, when tightening the legs 6a and 6b, the leg portions 6a and 6b are deformed by bending rather than compression, so that a small tightening force is required.
また前記抱持部６ｅの一方の上端部に前記カバー５の外
縁を覆う保合部６ｇを内方に屈曲させて形成することに
より、カバー５の外縁にその切断時に生じる突縁（いわ
ゆるぼり）に手を触れて怪我をすることを防ぐと共に、
シール材６のカバ−５外周部５ａに対する位置決めを確
実にし、さらにシール材６の脱落を防止している。Furthermore, by forming a retaining part 6g that covers the outer edge of the cover 5 by bending it inward at the upper end of one of the holding parts 6e, a protruding edge (so-called ridge) is formed on the outer edge of the cover 5 when the cover 5 is cut. In addition to preventing injury from touching,
This ensures the positioning of the sealing material 6 with respect to the outer peripheral portion 5a of the cover 5, and further prevents the sealing material 6 from falling off.
そして締付ボルトの代りに適宜の締結部材を用い得る。Further, an appropriate fastening member can be used instead of the tightening bolt.
前述したようにこの考案によれば、点検用カバー１を取

形量を適切にすることができ、シール材６の早期老化や
破損などを防止できる。As mentioned above, according to this invention, when the inspection cover 1 is removed, there are no protrusions around the opening of the cover main body 1, so the worker's clothes will not get caught during the maintenance inspection, or a spanner, etc. There is no problem in using the tool, and when the inspection cover 5 is attached, the amount of elastic deformation of the sealing material 6 can be controlled by the spacer 7, so the amount of deformation can be made appropriate, and the seal Early aging and damage of the material 6 can be prevented.
