A webbing retractor comprising: a spool to which a base end of a long strip-shaped webbing belt is engaged, and that takes up the webbing belt; a pressing member that moves in conjunction with the rotation of the spool, and presses an engaging member; a rotating body that is coaxial and rotatable relative to the spool; a locking member that engages with the spool and regulates the rotation of the spool in a pull-out direction of the webbing belt; the engaging member, which is arranged in the rotating body, and can move in an engaging direction to engage directly or indirectly with the spool and also in the opposite direction to the engaging direction, a rotation engaging member that is arranged in the rotating body, and rotates together with the rotating body in the pull-out direction of the webbing belt, and makes the locking member engage with the spool in accordance with the rotation; a connecting member that is arranged in the rotating body, and connects the rotating body with the spool, and makes the rotating body rotate in the pull-out direction together with the spool; characterized in that a space portion to house the pressing member is formed, and wherein in a state where the webbing belt is entirely pulled out from the spool, the pressing member is housed in the space portion; wherein the space portion is a notched portion that is formed in the engaging member, wherein the webbing belt is pulled out from the spool, the pressing member rotates in a pull-out direction and abuts the engaging member, and the pressing member further rotates in the pull-out direction to enter into the notched portion, whereby the entire length of the webbing belt is pulled out without a portion thereof being left in the spool. a spool to which a base end of a long strip-shaped webbing belt is engaged, and that takes up the webbing belt; a pressing member that moves in conjunction with the rotation of the spool, and presses an engaging member; a rotating body that is coaxial and rotatable relative to the spool; a locking member that engages with the spool and regulates the rotation of the spool in a pull-out direction of the webbing belt; the engaging member, which is arranged in the rotating body, and can move in an engaging direction to engage directly or indirectly with the spool and also in the opposite direction to the engaging direction, a rotation engaging member that is arranged in the rotating body, and rotates together with the rotating body in the pull-out direction of the webbing belt, and makes the locking member engage with the spool in accordance with the rotation; a connecting member that is arranged in the rotating body, and connects the rotating body with the spool, and makes the rotating body rotate in the pull-out direction together with the spool; characterized in that a space portion to house the pressing member is formed, and wherein in a state where the webbing belt is entirely pulled out from the spool, the pressing member is housed in the space portion; wherein the space portion is a notched portion that is formed in the engaging member, wherein the webbing belt is pulled out from the spool, the pressing member rotates in a pull-out direction and abuts the engaging member, and the pressing member further rotates in the pull-out direction to enter into the notched portion, whereby the entire length of the webbing belt is pulled out without a portion thereof being left in the spool.
