| 摘要 | In a power seat operation device, a micro switch is attached inside a dial that is rotatably provided to a side face of a power seat. An opening is formed inside the dial, with an operation portion of a knob to operate the micro switch inserted through the opening. There is accordingly a possibility that liquid might infiltrate into the dial, however a channel is formed inside the dial by the dial and the knob. The channel lets liquid flow downward to the lower side of the micro switch so as to discharge the liquid to outside the dial in cases in which liquid has infiltrated into the dial through the opening in a state in which the opening is positioned at the upper side of the micro switch. The channel is partitioned from the micro switch, enabling flow of liquid to the micro switch to be prevented or suppressed. | ||||||
