Patent ID: 7731117

Claim:
A webbing winding deice comprising: a spool at which a length direction base end of a long belt-form webbing belt is anchored, the webbing belt being wound, from the base end, onto the spool by rotation of the spool in a winding direction; a frame including a pair of leg plates which oppose one another in an axial direction of the spool; a first energy-absorbing member which is provided passing through the spool along the axial direction of the spool, the first energy-absorbing member deforming when a rotation force of at least a certain magnitude is applied to a portion of the first energy-absorbing member joined to the spool; a first locking mechanism which includes a rotor that is integrally joined to the first energy-absorbing member at one of the pair of leg plates and which, in a predetermined condition, restricts rotation of the rotor in an unwinding direction, which is opposite to the winding direction, and indirectly restricts rotation of the spool in the unwinding direction; a second locking mechanism which is disposed at the other of the pair of leg plates and which switches from a lock-release state to a locking state for restricting rotation of the portion of the first energy-absorbing member in the unwinding direction at the other of the pair of leg plates; a control mechanism which is provided passing through the spool along the axial direction of the spool, the control mechanism causing the second locking mechanism to switch into the locking state in accordance with relative rotation between the rotor and the spool; a first switching member which, by moving in a direction of withdrawal from an initial position, alters a state of at least one of the first locking mechanism and the second locking mechanism, and a restriction structure which restricts a return to the initial position of the first switching member that has withdrawn from the initial position, including a support member which supports the first switching member at the initial position from below, and a guide structure which guides the first switching member which is moved by gravity when support provided by the support mechanism is removed in a direction which is inclined relative to a vertical downward direction, and guides the first switching member to a position opposing the support member if the first switching member moves toward the initial position after withdrawing from the initial position.
