PROBLEM TO BE SOLVED: To make fitting structure of electric rod type and flexible type vibrating parts common so as to facilitate exchange of the vibrating part by fittingly connecting a driving shaft of a motor and a rotary shaft of the vibrating part, and clamp-fitting the motor and the vibrating part by a clamping cap. SOLUTION: A fit-in part 3 thread-fastened to a driving shaft 2 of a motor 1 is provided with a polygonal hole, and a tip part 9a of a connecting shaft 9 fitted to a rotary shaft 7 of an electric rod type vibrating part 5 through a joint fitting 8 is formed in polygonal cross section. The connecting shaft 9 is fitted into the fit-in part 3, and a clamping cap 11 is thread-fastened to a thread groove 4 of the motor 1 so as to fix a collar 10a of a keep member 10 made of vibration proof rubber and fitted to the tip of a pipe case 6, in pressure contact with the end face 1a of the motor 1, thus fixing the vibrating part 5 to the motor 1. In the same way, a flexible type vibrating part can be fixed to the motor 1. At a working site, the electric rod type and flexible type vibrating parts 5 can therefore be exchanged easily and used if necessary.
