Description
【考案の詳細な説明】 本考案は内燃機関のクランクケースに関する。[Detailed explanation of the idea] The present invention relates to a crankcase for an internal combustion engine.
この種クランクケースにおけるクランク軸の一

ネジ部又はオイルシールに泥をかみ易くネジ不良
又はシール不良を生じ易い不都合を有していた。 In this type of crankcase, the side cover at one end of the crankshaft is provided with multiple inspection holes such as a crank rotation hole or a timing peephole. When attaching and detaching each blind plug, there is a problem in that dirt tends to get stuck in the threaded portion or the oil seal, resulting in thread failure or seal failure.

たことを特徴とする。 The present invention is aimed at improving such inconveniences, and includes a crankcase for an internal combustion engine in which a plurality of inspection holes 3 are provided in a side cover 2 located at one end of a crankshaft 1.
The present invention is characterized in that a flat surface 4 in which a plurality of the inspection holes 3 are open is formed, and a sub-side cover 5 is attached which abuts on the flat surface 4 and blocks the plurality of inspection holes 3 at the same time.

b is a flat surface 4 formed on the outer surface of the side cover 2;
A sub-side cover 5 having the same shape as the flat surface 4 is integrally attached to the flat surface 4 by means of tightening screws 6. In the first figure, the timing peephole 3b is simply a through hole, and the sub-side cover 5 has a fitting protrusion 5 that can be fitted into the peephole 3b.
In the case shown in the second figure, another piece 7 made of an opaque material was previously inserted into the timing peep hole 3b to close the peep hole 3b. 8 in the figure indicates a generator attached to the crankshaft 1.

A flat surface 4 is formed in which a plurality of inspection holes 3 are opened, and a sub-side cover 5 is attached which contacts the flat surface 4 and blocks the plurality of inspection holes 3 at the same time. Since the inspection hole 3 does not require a blind plug, it is easy to cover the inspection hole 3 without avoiding screw defects or oil seal defects when installing and removing the blind plug, and the sub-side cover 5 does not require a blind plug. Since there are no such restrictions, the shape can be freely selected.
