Abstract

PURPOSE:To fit the receiver of a transmitter and receiver to a housing easily and securely, by rotating the receiving part after inserting it into the opening part of the housing, and dropping its fitting piece in the fitting groove of a housing side. CONSTITUTION:When a fitting piece 5 is positioned at a cut part 21 and a receiving part A is inserted into the opening part 20 of a housing B, the reverse surface of the receiving part A is supported in contact with the circumferential edge part 20a of the opening part. When the receiving part A is rotated in one direction, the fitting piece 5 positioned in the cut part 21 moves forth, as shown by an arrow, on the slanting surface of a locking projection part 22 and then gets over the part 22 to be fitted in a fitting groove 23. As a result, the lower part of the receiving part A is locked to the housing B at four positions, and positioned and fixed securely.
