PROBLEM TO BE SOLVED: To provide a motor which can secure lubricating oil for a long term and has a simple construction. SOLUTION: A stator S, a rotor R which is turned relatively to the stator S by current application with a shaft as the center of rotation, an oil- impregnated metal bearing 2 which is placed in the housing member 1 of the stator S, supports the rotary shaft 3 of a rotor R so as to be able to rotate relatively to the stator S and composed of a shaft output side oil-impregnated metal bearing part 2X and a counter output side oil-impregnated metal bearing part 2Y which are integrally coupled with each other into an approximately cylindrical shape and a holding means 80 with a recess which holds the counter output side oil-impregnated metal bearing part 2Y and, further, holds the tip part of the shaft 3 of the rotor R rotatably are provided.
