PROBLEM TO BE SOLVED: To prevent intrusion of lubricating oil into a working space as much as possible by providing a cross guide with a hole connecting between the crankshaft chamber side and the sealed section side at a position on the side where lubricating oil is not splashed by a rotating crankshaft. SOLUTION: Interconnecting holes, e.g. cuts 64a, 64b, are made at an upper part of a cross guide 19. The cuts 64a, 64b, are made at a position on the side 70 where lubricating oil is not splashed by a rotating crankshaft. Consequently, when lubricating oil is splashed by a rotating crankshaft, a sealed section can be prevented from being splashed directly with lubricating through the cuts 64a, 64b. According to the structure, excessive supply of lubricating oil to the sealed section can be prevented.
