Each terminal () of a bulb socket () has a power-supplying tab () and a bulb connecting portion () that are integral with one another. The bulb connecting portion () is on an extension of the power-supplying tab () extending along an inserting direction into a connector accommodating portion (). Thus, the bulb socket () is reduced in height, the number of assembling steps is reduced, and the deformation of the terminals can be avoided. Further, a reduction in the number of parts leads to reduced production costs.

L-shaped bulb socket

A connection body ( ), of a connector for a towing vehicle, to be connected to a wire harness of a to-be-towed object and a connection body ( ) of the connector to be connected to a wire harness of a towing vehicle body are approximately cylindrical. Terminals ( ) inside the connection bodies ( ) are composed of a common metal piece ( ). The connector is connected to a wire harness ( ) of the towing vehicle body not by using an exclusive cylindrical connector but by directly connecting a core wire to the terminal ( ). To prevent water from penetrating into the connector, an O-ring ( ), a sealing medium ( ), and a rubber plug ( ) are mounted on the connector. A protector ( ) is installed on an insertion portion of the wire harness ( ) of the towing vehicle body into the housing ( ).
