    • PROBLEM TO BE SOLVED: To provide a power generation device for a clock capable of acquiring a constant torque with an input-output structure similar to an incense box, and the incense box and a clock using the same.SOLUTION: An incense box 1 being a power generation device of a clock 2 has a holder 5 supported rotatably with respect to a support, first and second winding shafts 6, 7 supported rotatably by the holder at the center of rotation and an eccentric position of the holder, respectively, and a spiral spring 8 in the form of an elastic belt-like body 50 in which both ends 51, 52 constitute a constant torque between the first and second winding shafts. When the spiral spring is wound around one of the first and second winding shafts to restrict the rotation of the holder with respect to the support, the first winding shaft is rotated to wind the spiral spring around the first winding shaft, and when the spiral spring is wound around the other of the first and second winding shafts to restrict the rotation of the first winding shaft with respect to the support, the holder is rotated with respect to the first winding shaft to output power.
    • 要解决的问题:提供一种能够通过类似于香炉的输入 - 输出结构获得恒定转矩的时钟的发电装置,以及使用其的钟盒和钟。解决方案:一个香炉1 时钟2的发电装置具有相对于支撑件可旋转地支撑的保持器5,分别由保持件可旋转地支撑在支架的中心和支架的偏心位置的第一和第二卷绕轴6,7, 弹性带状体50的形式的螺旋形弹簧8,其中两端51,52构成第一和第二卷绕轴之间的恒定扭矩。 当螺旋弹簧卷绕在第一和第二卷绕轴中的一个上以限制保持器相对于支撑件的旋转时,第一卷绕轴旋转以使螺旋弹簧围绕第一卷绕轴缠绕,并且当螺旋弹簧 围绕第一和第二卷绕轴的另一个缠绕以限制第一卷绕轴相对于支撑件的旋转,保持器相对于第一卷绕轴旋转以输出动力。
