Abstract
An actuator includes an attachment member including a coil; a movable element having a magnet disposed opposite to the coil, and that is displaced relative to the attachment member when the coil is energized; a resilient support; and a cushioning material. The resilient support has an attachment member-side fixing portion that is fixed to the attachment member, a movable element-side fixing portion that is fixed to the movable element, and a deformation portion that links the attachment member-side fixing portion and the movable element-side fixing portion. The cushioning material is provided between the attachment member and the deformation portion, and deforms in conjunction with bending deformation of the deformation portion.
Claims11
An actuator, comprising:
- an attachment member including a coil;
- a movable element having a magnet disposed facing the coil, the movable element being displaced relative to the coil by energization of the coil;
- a resilient support having an attachment member-side fixing portion that is fixed to the attachment member, a movable element-side fixing portion that is fixed to the movable element, and a deformation portion that links the attachment member-side fixing portion and the movable element-side fixing portion;
- and
- a cushioning material provided between the attachment member and the deformation portion, the cushioning material deforming in conjunction with bending deformation of the deformation portion,
- wherein the cushioning material is a discrete member from the resilient support.
