クラッチ装置及び該クラッチ装置を用いたモータユニット
Document Type and Number:
Japanese Patent JP6738987
Kind Code:
B2
Abstract:
A clutch device includes an input disc, an output disc, and a biasing member configured to press the input disc against the output disc. A rotation load applied to an output shaft separates the input disc from the output disc against biasing force of the biasing member. The input disc and the output disc include opposing surfaces, each of which includes axially disengageable overlapping tooth portions. Recessed and raised portions of each tooth portion are formed continuously in a radial direction and are alternately arranged in a circumferential direction. Each of the curved shapes of the recessed and raised portions is maintained at a respective identical height while a circumferential width thereof continuously expands in a radially outward direction. Also disclosed is a motor unit including the clutch device. The disclosed clutch device reduces, e.g., deformation or damage of a disengageable portion, and therefore, can improve durability.
