WEBBING TAKE-UP DEVICE
First Claim
1. A webbing take-up device comprising:
- a spool that takes up a webbing worn by an occupant;
a first rotating body that is rotated by rotation force being transmitted thereto;
a second rotating body that rotates the spool by the second rotating body being rotated;
a clutch that is provided between the first rotating body and the second rotating body, and that transmits rotation force of the first rotating body to the second rotating body by the clutch being rotated by the first rotating body; and
a sub clutch that is provided between the first rotating body and the clutch, that transmits rotation force of the first rotating body to the clutch in a case in which the first rotating body is rotated toward one side, and that blocks transmission of the rotation force of the first rotating body to the clutch in a case in which the first rotating body is rotated toward another side.

Abstract
A webbing take-up device includes a spool that takes up webbing worn by an occupant, an input gear that is rotated by rotation force being transmitted, a spool gear that rotates the spool by being rotated, and a second clutch that is provided between the input gear and the spool gear, and that transmits rotation force of the input gear to the spool gear by being rotated by the input gear. The webbing take-up device further includes a sub clutch spring that is provided between the input gear and the second clutch, that transmits rotation force of the input gear to the second clutch when the input gear is rotated toward one side, and that shuts off transmission of rotation force of the input gear to the second clutch when the input gear is rotated toward another side.
