A tape-like driving force transmitting member is used in a passive seat belt to guide a webbing automatically between a passenger-restraining position and a passenger-releasing position. A plurality of notches is spacedly formed in at least one side edge of the driving force transmitting member. Owing to the provision of the notches, the driving force transmitting member of this invention can be bent readily not only in its thickness direction but also in its width direction, thereby allowing the driving force transmitting member to move smoothly.
