変不便で、整備等の手間がかかることがある。 Generally, in motorcycle engines, a collar with multiple bolt holes is welded to the end of the exhaust pipe, the end of the exhaust pipe is aligned with the exhaust hole end of the engine block, and the bolts are inserted through the bolt holes in the collar. is fastened to a screw hole provided around the end of the exhaust port of the engine block to connect the exhaust pipe to the engine block. However, a frame pipe may pass through the exhaust pipe, or parts such as a radiator may be located near the exhaust pipe. In this case, the outer bolt can be tightened with a spanner, but the inner bolt may not be tightened. Even in this case, a special spanner such as a box spanner may be inserted, but this may not be possible, and each time an inner bolt is attached or detached, parts attached near the radiator etc. must be attached or detached in order to be able to be attached or detached. , which can be very inconvenient and require a lot of maintenance.
この発明は、かかる点に鑑み、エンジンブロツ
クに連結する排気管を一方の側からの作業で着脱
できるように改善したもので、以下本発明を図面
に示す実施例について説明する。 In view of this problem, the present invention has been improved so that the exhaust pipe connected to the engine block can be attached and detached by working from one side.Hereinafter, an embodiment of the present invention shown in the drawings will be described.
エンジンブロツク１の排気孔２の端に、一側が
開放したＵ字状の溝３を有する突出部を設ける。
一方、排気管４の端には後面が傾斜５した鍔６を
溶着する。排気管４は、端面に環状のガスケツト
７を当て、鍔６を溝３に挿入して排気孔２に合せ
る。又、先端が二又になり、厚さが先に行くに従
つて薄くなつた楔片８を設け、楔片８を、溝３に
挿入する。楔片８は、ボルト９で、溝３の端面部
分に締着する。 A protrusion having a U-shaped groove 3 with one side open is provided at the end of an exhaust hole 2 of an engine block 1.
On the other hand, a collar 6 whose rear surface is inclined 5 is welded to the end of the exhaust pipe 4. An annular gasket 7 is applied to the end surface of the exhaust pipe 4, and the collar 6 is inserted into the groove 3 to fit into the exhaust hole 2. Further, a wedge piece 8 is provided which has a bifurcated tip and whose thickness becomes thinner as it goes forward, and the wedge piece 8 is inserted into the groove 3. The wedge piece 8 is fastened to the end face portion of the groove 3 with a bolt 9.
しかして、排気管４の鍔６を溝３に挿入し、楔
片８が、鍔６の傾斜５した面に重なるように楔片
８を溝３に挿入して、楔片８をエンジンブロツク
１に締着すると、傾斜５の面によつて、鍔６は軸
方向分力によつて、ガスケツト７を押えて排気孔
２の端面に押付けられて締着できる。Ｕ字状の溝
３の開放口を、操作し易い外側に向けることによ
つて、楔片８を締着するボルト９は、外側からだ
けで、着脱できる。 Then, insert the flange 6 of the exhaust pipe 4 into the groove 3, insert the wedge piece 8 into the groove 3 so that the wedge piece 8 overlaps the inclined surface 5 of the flange 6, and then insert the wedge piece 8 into the engine block 1. When the gasket 7 is tightened, the flange 6 is pressed against the end face of the exhaust hole 2 by the axial component force due to the surface of the slope 5, and can be tightened. By directing the opening of the U-shaped groove 3 toward the outside for easy operation, the bolt 9 that fastens the wedge piece 8 can be attached and removed only from the outside.
以上説明したように、この発明は、エンジンブ

で、楔片の楔作用で、排気管端の鍔が、排気孔端
に押付けられて、密着し、排気ガスが洩れないよ
うに確実に連結できる。そして、溝の開放した側
を操作の都合のよい外向き等に選ぶことによつ
て、その方向に楔片を締着するボルトが位置し、
スパナが楽に掛けられて、着脱作業が容易にな

も、着脱できてエンジンの整備性の向上が図れ
る。 As explained above, the present invention provides a U-shaped groove with one end open at the end of the exhaust hole of an engine block, inserts a flange with an inclined rear surface provided at the end of the exhaust pipe into the groove, and Since the wedge piece fastened to the open side of the exhaust hole is engaged with the inclined surface of the flange, the flange at the end of the exhaust pipe is pressed against the end of the exhaust hole due to the wedging action of the wedge piece, and the flange is brought into close contact with the end of the exhaust hole. , can be connected securely to prevent exhaust gas from leaking. Then, by selecting the open side of the groove to face outward for convenience of operation, the bolt for tightening the wedge piece is positioned in that direction.
A wrench can be easily applied, making attachment/detachment work easier. Even if nearby parts remain attached, they can be attached and detached, improving the maintainability of the engine.
