A webbing take-up device ( 10, 100 ) is disclosed, wherein a motor ( 44 ) is provided directly below a take-up shaft ( 20 ) between a pair of leg plates ( 16, 18 ) with a rotary shaft ( 50 ) of the motor ( 44 ) disposed perpendicularly to the take-up shaft ( 20 ), and a clutch ( 26 ) is provided at one side of one leg plate ( 16 ). Further, a gear ( 76 ) of a motor gear portion ( 46 ) is removably connected to a worm gear ( 34 ) in a clutch gear portion ( 28 ), and a mounting stay ( 84 ) is detachably attached to a case ( 30 ) with screws ( 86 ), so that the motor ( 44 ) and the motor gear portion ( 46 ) can be detached independently of the case ( 30 ) while still being assembled together. Still further, a pretensioner mechanism ( 156 ) and a sensor mechanism ( 182 ) are provided at one end side of a spool ( 118 ), and an urging mechanism ( 136 ) is disposed at the other end side thereof.
