摘要： This invention relates to a rotation sensor which detects the magnetic field which changes with the rotation of a rotary shaft, thereby to detect the amount of rotation of the rotary shaft. The rotation sensor of the present invention has the boundaries between magnetized regions set with high precision. The boundaries forms magnetic fields stably, whereby the detection of rotation is performed with high accuracy.

摘要： An actuator for use in an air bag device which is inflated by a gas as a firing pin is moved by the movement of an inertia member to actuate a gas generator and in a preloader of a webbing retractor actuated by the gas. A contact is provided for outputting an electrical signal by being turned on at the time of movement of the inertia member or movement of the firing pin. Accordingly, by providing another gas generating means adapted to be actuated in correspondence with an output of this contact, it is possible to actuate a plurality of air bag devices or preloaders.
