Abstract

The invention provides a coil unit and a driving mechanism. This coil unit can easily perform the work of attaching the coil to the coil holding member. The coil unit (35) includes an even number of coils (26) and a coil holding member (9) holding the even number of coils (26). A side pair consisting of a pair of side surfaces substantially parallel to each other is formed on the outer peripheral surface of the coil holding member (9), and the outer peripheral surface of the coil holding member (9) is composed of two or more side pairs. In the coil unit (35), a convex portion (9e) is formed on the side surface of the coil holding member (9) so as to protrude toward the outer peripheral side of the coil holding member (9), and the coil is directly wound on the convex portion (9e). There is one coil (26), and the two coils (26) wound on the side-facing protrusions (9e) of the coil holding member (9) are constituted by one wire.

Description

technical field [0001] The present invention relates to a coil unit including a plurality of coils and a coil holding member for holding the plurality of coils, and a drive mechanism including the coil unit. Furthermore, the present invention relates to a winding device for winding a coil around a coil holding member, and a winding method for winding a coil around the coil holding member using the winding device. Background technique [0002] Conventionally, there is known an imaging optical device having a camera shake correction function for correcting camera shake or the like (for example, refer to Patent Document 1). The imaging optical device described in Patent Document 1 includes: a movable module having a lens and an imaging element; a support body that supports the movable module in a swingable manner; a leaf spring connecting the movable module and the support body; A swing drive mechanism that swings the movable module relative to the support body through correct...
