Abstract
PURPOSE: To prevent seizure of a bearing from being caused by oil film shortage due to oscillations by composing a bearing of a center, bearing member which is fitted to an inner peripheral surface of a divided housing, which bearing rotatably supports an eccentric shaft.
CONSTITUTION: An intermediate housing 5 which is arranged on a portion corresponding to a central part of an eccentric shaft 28 is divided into a first housing 5a and a second housing 5b sequentially from the central part in an axial direction of the eccentric shaft 28. A bearing member 60 as a center bearing member is provided on an outer periphery of a main eccentric shaft 21 corresponding to the intermediate housing 5, through a metal 59 as a bearing part. A clearance is formed between the outer peripheral surface of the bearing member 60 and an inner peripheral surface of the intermediate housing 5 so as to alleviate stress concentration between the bearing member 60 and the intermediate housing 5 caused by oscillations of the eccentric shaft 28. Lubricating oil is supplied to the metal 59 through the second housing 5b and a lubricating oil passage 65 formed on the bearing member 60.
