Abstract
A case that houses a chain includes a first cover member fixed to a cylinder block and a cylinder head, and a second cover member arranged on the opposite side of the cylinder block and the cylinder head from the first cover member. In an intermediate part, which is a part of a confronting wall of the first cover member between the first flange and the second flange, a cover-side rib is provided, having a height so that a distal end of the cover-side rib is not in contact with the cylinder block.

An internal combustion engine, comprising:
- a first cover member fixed to a cylinder block and a cylinder head;
- a second cover member arranged on the opposite side of the cylinder block and the cylinder head from the first cover member;
- an endless transmission member that transmits rotation of a crankshaft to a camshaft provided in a space defined by the first cover member and the second cover member;
- a first flange, which is provided in a confronting wall of the first cover member and projects on the cylinder block side, in which a distal end of the first flange is in contact with the cylinder block, the confronting wall forming a surface that faces the cylinder block and the cylinder head;
- a second flange that is provided at a position separated from the first flange and projects on the cylinder head side, in which a distal end of the second flange is in contact with the cylinder head;
- and
- a first rib that is provided in an intermediate part, which is a part of the confronting wall of the first cover member between the first flange and the second flange, and projects on the cylinder block side, in which a distal end of the first rib is not in contact with the cylinder block.
