Abstract

A webbing take-up device is provided capable of preventing or suppressing a frame from deforming such that one of leg-plates or a back-plate displaces towards the other. A face on the center of curvature side of a curved portion of a front back plate section configuring the frame and a one width direction edge namely an upper edge of a bar support face each other along the up-low direction. When the front edge sides of leg-plates are displaced to rise due to a webbing being pulled, the one width direction edge of the bar support interferes with a front end of the front back plate section to prevent or suppress the front edge sides of the leg-plates from rising further. Deformation of the frame caused by the front edge sides of the leg-plates to rise can accordingly be prevented or suppressed.

Claims9

Dependent claims

A webbing take-up device comprising:

a frame in which a pair of leg plates extend from a plate shaped back plate towards one side in a thickness direction of the back plate;
a spool that is provided between the pair of leg plates, an axial direction of the spool being along a facing direction of the pair of leg plates and both ends of the spool being directly or indirectly supported by the pair of leg plates;
a webbing having a base end that is anchored to the spool, the webbing being pulled out towards the other side which is an opposite side from the one side in the thickness direction of the back plate and extending along the back plate;
and
an interfering member that is provided at the leg plates at the one side in the thickness direction of the back plate with respect to the back plate, the interfering member interfering with the back plate so as to restrict deformation of the frame in a direction in which the leg plates approach the back plate,
wherein the interfering member is normally separately spaced apart from the back plate, and contacts the back plate only when the leg plates are displaced as a result of the webbing being pulled forcefully from the spool.
