Abstract: An inclination controlling mechanism of a seatbelt device is provided with: a pulley that converts an advancing/retracting movement of a cable of the cable advancing/retracting mechanism; a drive gear mounted around a pivot shaft of the pulley and synchronized with rotation of the pulley; and a driven gear mounted around a pivot shaft of a sensor housing so as to move in conjunction with a rotation of the sensor housing. The drive gear and driven gear engage with each other in a condition where a rotational track surface of the drive gear and rotational track surface of the driven gear intersect at a predetermined angle. As a result, an inertial body supporting surface serving as a sensor reference plane can be accurately maintained horizontally even at an arbitrary seatback recline angle, and thus the accuracy of the acceleration sensor can be improved.
