Abstract
Connector terminals 13 connected to ends of respective electric wires 12 are inserted into an electric wire insertion section 11b formed in a housing body 11 of a waterproof connector 10. The connector terminals 13 are attached to respective terminal attachment sections 11a. The connector comprises a plug 14 which is molded on the outer peripheral surfaces of the electric wires 12 situated in the electric wire insertion section 11b and which is removably fitted into the electric wire insertion section 11b with a slight gap between the inner peripheral surface of the electric wire insertion section 11b and the plug 14; and a resiliently-deformable annular sealing body 15 which is retained in a retention groove formed along an outer peripheral surface of the plug 14 and which is brought into intimate contact with the inner peripheral surface of the electric wire insertion section 11b.
