Abstract

PURPOSE:To form the towing receiver greater in the mechanical strength, by using the mixture of rubber and plastic and electroacoustic conversion element as receiving element, or using plastic electroacoustic conversion element. CONSTITUTION:Between the tension member 1 of line shape and the receiving element 3 of pipe shape, the output cable 2 is incorporatedly formed. As the element 3, the mixture of the electroacoustic conversion element and rubber or plastic, or plastic electroacoustic conversion element is used. This is contained in the vinyl hose 5 via a spacer 4 and light oil 6 is filled in as floating member agent. Thus, the towing receiver ease of manufacture and assembling and greater in mechanical strength can be obtained.
