PROBLEM TO BE SOLVED: To provide a vibratory bowl feeder that includes an elastic member extending horizontally and vibrating in a horizontal rotation direction, in which a stress load on the elastic member is reduced and a component supply capability is improved.SOLUTION: A rotational vibration plate spring (elastic member) 3 extending horizontally and vibrating in a horizontal rotation direction is disposed by forming a predetermined angle &thetas; in a horizontal plane so that an inside fixed position approaches more than an outside fixed position with respect to a horizontal virtual reference line X extending radially from a rotation center Z of an upper vibrator 2 and a lower vibrator 6. Accordingly, a locus in a virtual free state of the fixed position outside the rotational vibration plate spring 3 during vibration is made to get close to a locus in a real fixed state, in comparison with the case when disposed in parallel to the virtual reference line X, so that a tensile force acting on the rotational vibration plate spring 3 and respective elastic member mounting parts 2a, 4a for fixing the spring during the vibration is reduced, thereby reducing a stress load to these components to achieve high-speed supply. |
