PROBLEM TO BE SOLVED: To solve a neck breaking phenomenon generated in a vibration proof rubber between a motor and a vibration body in a concrete vibrator. SOLUTION: In a concrete vibrator wherein a rod shaped vibration body B is connected to a rotaty shaft of a motor with a handle interposing vibration proof rubber C, a shape holding metal fitting 11 is integratedly formed with the vibration proof rubber C so as to prevent the vibration proof rubber C from bending. Hereby, since the bending of the vibration proof rubber is solved by the shape holding metal fitting, rubber in which hardness is low and an isolation effect is high can be used.
