電動式操作装置
Document Type and Number:
Japanese Patent JP7212931
Kind Code:
B2
Abstract:
To provide an electric operating device capable of manually switching a drain port from an open state to a closed state at the time of a power failure or the like while improving the degree of freedom related to installation.SOLUTION: An electric operating device 3 includes: a first transmission piece 3331 having a locking portion and a second transmission piece 3332 having a locked portion; and the plug cover moves up and down by a force applied from the locking portion to the locked portion, and the open/closed state of the drain port is switched. Further, by the clutch mechanism, when a relatively large load is applied from the plug cover side to the second transmission piece 3332, the locking of the locking portion with respect to the locked portion becomes insufficient, and the second transmission piece 3332 can be operated independently with respect to the first transmission piece 3331. Thus, by applying a downward force to the plug cover when the drain port is open, the second transmission piece 3332 operates independently while the locking of the locking portion with respect to the locked portion is in an insufficient state. Thus the plug cover can be moved downward.SELECTED DRAWING: Figure 9
