Title:
ROTARY TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2021153570
Kind Code:
A
Abstract:
To provide a rotary transmission device capable of minimizing force for loosening a spring and rotating after direct coupling from an input shaft to an output shaft, for achieving preferable rotary transmission efficiency and being used easily.SOLUTION: A step shaped base end step part 11 and a tip end step part 12 comprising a space for storing respectively, a hook part 30, 31 provided on one/the other of both ends of a brake spring 3, in a free motion state, are provided on a base end and tip end of a rotary transmission part 10 of an input shaft 1, and the base end step part and the tip end step part are formed inside of both side edge part 14 of the rotary transmission part 10 and respective hook parts 30, 31 of the brake spring 3 are stored in one/the other of the base end step part 11 and the tip end step part 20, and are slightly movable inward of a vertical direction, and in a state in which excessive force is not applied to an output shaft 2, a part 20 to which rotation is transmitted of the output shaft 2 is pressed while the brake spring 3 is pressed thereby shrinking a diameter of the same brake spring 3.SELECTED DRAWING: Figure 1
