Abstract
A seat belt device includes a spindle () for retracting a seat belt (), an electric actuator (), a pre-tensioner () and a power transmission mechanism (), wherein the power transmission mechanism () can reversibly switch the connection and disconnection between the electric actuator () and the spindle () before the pre-tensioner () is activated, while when the pre-tensioner () is activated. The power transmission mechanism () non-reversibly interrupts the connection between the electric actuator () and the spindle () via an elastic piece () when a torque difference between an actuator-side gear () and a spindle-side gear () becomes larger than a predetermined value.
