PURPOSE:To prevent a bearing from getting seizure or binding, by setting up an oil pan in and around the inside of a casing, while installing one end of the oil pan extendedly in a casing end face at the bearing attached side, and forming an oil feed passage in a bearing housing part from the casing end face. CONSTITUTION:An oil pan 50 is set up an around the inside a casing 40 and one end of the oil pan 50 is installed extendedly in a casing end face at the side where the casing 44 is attached, then an oil feed passage 60 is formed in a bearing housing part 54 from a terminal part of the oil pan 50 on the casing end face. With this constitution, even in case of a bearing setting structure being closed at both sides, lubricating oil being scattered inside the casing 40 is gatherable and feedable to a bearing part so that seizure or binding due to a shortage of lubrication is preventable from occurring.
