摘要： In this buckle device, a base end portion of a belt is folded back on itself to form a ring-shaped portion, and the belt is wound onto a spool in a state in which the ring-shaped portion of the belt has been inserted through an insertion hole in the spool. This enables a winding radius of the belt to be increased by the base end portion of the belt and enables a load at which the belt is permitted to be pulled out to be reduced, when the belt is pulled out from the spool.

摘要： In a buckle device, when a belt starts to be allowed to be drawn, a fracture portion is deformed by a side surface of a connection hole of a spool, so that the fracture portion allows a rotation of the spool and allows drawing of the belt. Then, the fracture portion is fractured by the side surface of the connection hole. Therefore, a drawing allowance load of the belt when the belt starts to be allowed to be drawn can be increased.

摘要： In the buckle device, when or after torsional deformation of the torsion shaft has started and allowance of the drawing-out of the belt has started, the breaking portion of the shear plate is started to be deformed by the coupling hole side surface of the spool, whereby the breaking portion allows the rotation of the spool and allows the drawing-out of the belt. Therefore, the allowable drawing-out load of the belt can be made the sum of the load for torsionally deforming the torsion shaft and the load for deforming the breaking portion, and can be increased.

摘要： In this buckle device, when a second wind of a belt is pulled out from a spool, a load at which the belt is permitted to be pulled out is small, whereas slide resistance of the belt with respect to a slide face is large. When a first wind of the belt is then pulled out from the spool, the belt pull-out permitting load is large, whereas the slide resistance of the belt with respect to the slide face is small. This enables variation in a load at which extending of a buckle body is permitted to be suppressed.

摘要： Webbing guide includes: guide body through which webbing is inserted; front wall that contacts one side face of first opening edge part and second opening edge part; rear wall that contacts another side face of first opening edge part; and claw that contacts another side face of second opening edge part. Connection part connects guide body and rear wall and includes concave part, and leading end of first opening edge part enters into concave part when webbing guide is assembled with member for assembly.
