Document Type and Number:
Japanese Patent JP2017104362
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a liquid infiltration prevention structure of a rotary connector part capable of preventing a liquid from infiltrating an inside of a connecting connector even when the liquid leaks to the connecting connector side.SOLUTION: A liquid infiltration prevention structure of a rotary connector part discharges a liquid from a connection mechanism 90 for connecting an ultrasonic sensor unit for performing radial scan and a drive part 65 for driving the ultrasonic sensor unit to rotate, and prevents the liquid from infiltrating into the rotary connector part. The connection mechanism 90 comprises a connecting connector 70 for structurally and electrically connecting the drive part 65 to the ultrasonic sensor unit, and a cylindrical body 80 surrounding the outside of the connecting connector 70, whose end part on the ultrasonic sensor unit side is open. The cylindrical body 80 is arranged in a space connected to the inside of the ultrasonic sensor unit. The cylindrical body 80 comprises a discharge hole 85 communicating the inside and the outside thereof.SELECTED DRAWING: Figure 2
