摘要： A motor includes a rotor having an output shaft and a rotor main body, a bearing member for supporting the output shaft movable in an axial line direction and rotatable around the axial line, and a bearing holding member holding the bearing member. The bearing member has a tube part supporting the output shaft and a slidably contacting part capable of slidably contacting with the rotor main body. The bearing holding member has an opposed face facing the rotor main body and a recessed part provided in the opposed face. The tube part of the bearing member is inserted into the recessed part and is separated from a bottom face of the recessed part. A space between the bottom face of the recessed part and the tube part is structured as a lubricant storage part and a communication path is provided between the bearing holding member and the bearing member.
