Title:
VIBRATION ACTUATOR
Document Type and Number:
Japanese Patent JP2022072471
Kind Code:
A
Abstract:
To provide a vibration actuator having excellent vibration characteristics that facilitates positioning of a leaf spring and a weight and neither causes abnormal vibration nor generates abnormal noise.SOLUTION: The vibration actuator is constituted of: a cylindrical case 2; a coil 21 provided in the case 2; a movable element 4 that is vibrated along a vibration axis line O of the case 2 by the coil 21; and two leaf springs 5 whose outer periphery portions are fixed to the case 2 and whose inner periphery portions are fixed to the movable element 4. The movable element 4 is provided with a polygonal central axis 324 protruding in a direction of the vibration axis line O. The leaf spring 5 has a polygonal axial hole 50, formed in the center of the inner periphery portion, to which the central axis 324 is fitted.SELECTED DRAWING: Figure 3
