This invention is novel structure of an over-current protection device and manufacturing method thereof. Further, a cylinder chamber 18 in the rear of the direct-acting type actuator section 10 is connected to a cylinder chamber 38 in the rear of the oscillating type actuator 30 through a stop valve 50. The hollow shaft is rotatable about an axis intersecting with an optical axis of the lens. The ring gear is selectively lockable, via a coupling means, in a first coupling position in which the gear is non-rotatably connected to the housing in order to establish gearing between the input shaft and the output shaft, and in a second coupling position in which the gear is non-rotatably connected to one of the input shaft and the output shaft in order to establish direct drive therebetween. An exhaust gas-purifying catalyst of the present invention includes a composite oxide of alkaline-earth metal and aluminum, and platinum, wherein at least a part of the composite oxide and at least a part of the platinum forms a solid solution.
