PROBLEM TO BE SOLVED: To provide a damper gear which enables reduction of a linear dimension in a direction along an axis to save an arrangement space of the damper device.SOLUTION: A damper gear 20 includes: an input side cylindrical member 30 formed into a cylindrical shape and in which openings 33 and spring contact parts 34 are alternately provided over a circumferential direction; an intermediate cylindrical member 40 formed into a cylindrical shape and in which openings 41 and spring contact parts 42 are alternately provided over the circumferential direction; and an output side cylindrical member 50 formed into a cylindrical shape and in which openings 53 and spring contact parts 54 are alternately provided over the circumferential direction. The intermediate cylindrical member 40 is inserted into an inner space of the input side cylindrical member 30, and the output side cylindrical member 50 is inserted into an inner space of the intermediate cylindrical member 40. Main damper springs 70, 80 are arranged in spring arrangement spaces formed between spring contact parts 34, 42, 54 of the cylindrical members 30, 40, 50. The structure enables reduction of a linear dimension in a direction along an axis in the serial spring type damper gear 20 to save its arrangement space.SELECTED DRAWING: Figure 1 |
