Abstract
A crankcase is coupled to a lower end face of a cylinder block of an engine and includes first and second case halves coupled to each other in a plane perpendicular to joint surfaces of the cylinder block and the crankcase. A U-shaped seal groove is defined in one of the joint surfaces of the case halves. Enlarged recesses are made at opposite ends of the seal groove. A bar-shaped seal member having enlarged end portions formed at opposite ends thereof is mounted in the groove such that the enlarged end portions are filled in the enlarged recesses. Thus, it is possible to ensure accuracy of the positioning of the bar-shaped seal member without the need for a high level skill; thereby, reliably sealing portions of intersection between the joint surfaces of the cylinder block and the crankcase and the joint surfaces of the case halves of the crankcase.
