PURPOSE:To improve and stabilize strength for holding a bearing by providing the bearing equipped with a clutch mechanism which prevents a gear case from being rotated in the reverse rotating direction of dewatering at the time of washing, extending the housing part of a bearing case from a bottom part to an upper direction and forming an upper surface on the same surface as the upper surface of the clutch mechanism. CONSTITUTION:For a clutch switching device 2, the inner diameter of a bearing 21 equipped with a clutch mechanism 21a, which outer diameter is fitted to a bearing case 15, and a bearing part 21b is fitted to a gear case 12. A housing part 15a is composed of an extended part 15a-1 which is extended upward rather than a bottom part 15b, holding part 15a-2 of the clutch mechanism part 21a and holding part 15a-3 of the bearing part 21b. In order to improve the holding strength of the holding part 15a-2 for the clutch mechanism part 21a and the housing part 15a, the radial strength of the housing part 15a is required and by extending the housing part upward to form a step push part 15c, the purpose is achieved.
