Abstract: A webbing retractor 10 has a structure in which a housing 48, to which a motor 44 is attached, faces in an axial direction of a worm gear 34, and is assembled and fixed to an end face of a case 30 which is orthogonal to a direction of thickness of the case 30, in which a clutch 26 which is attached in a joined state to a side face of one leg plate 16 is accommodated, and at an opposite side from a back plate 14. Moreover, this is a structure in which a rotation shaft of the motor 44 is between the leg plate 16 and a leg plate 18 in a state of being orthogonal to a winding shaft 20, and the motor 44 is disposed directly below the winding shaft 20.
