A seat belt apparatus is provided which includes a retractor having an electric motor to retract or draw out a seat belt, a motor information detecting means to detect an amount of rotation and a current value of the electric motor, a first condition detecting means to detect that an ignition switch is in an OFF state, a second condition detecting to detect that a getting on/off door located nearest to a seat to which a seat belt is attached is opened, a failure diagnosis timing judging means to start a failure diagnosing operation when a detecting signal is output from both the condition detecting means, and a failure diagnosing means to apply a driving current to the electric motor when the failure diagnosing operation is stated and to carry out a failure diagnosis of a driving system including a electric motor based on an output, in response to the application of a current, from the motor information detecting means. By configuring as above, the failure diagnosis can be carried out without causing a feeling of abnormality of discomfort to a vehicle occupant.
