PROBLEM TO BE SOLVED: To provide a slide bush suitable for miniaturizing a device and reducing the number of working man-hours by forming the slide bush into the cylindrical shape having the approximately uniform outer diameters from one end surface to the other end surface, and forming a recessed part covering an opening of an oil feed passage and communicated to an inner peripheral surface of the slide bush on a lower end surface of the slide bush. SOLUTION: An approximately cylindrical slide bush 1 is freely engaged with an eccentric part 2a of a crankshaft 21 communicated to a rotor of a motor. The slide bush 1 has the cylindrical shape having the approximately uniform outer diameter from an upper end surface to a lower end surface, and does not have a flange part. The slide bush 1 comprises a recessed part 1a on its lower end surface, and this recessed part 1a is communicated to an inner peripheral surface of the slide bush 1. The recessed part 1a is formed into the shape of a crescent avoiding a diagonal groove formation area, communicated to the inner peripheral surface and a cutout part of the slide bush 1, and covers an opening end of an oil feed passage 2b formed on a crankshaft 2.
