DRIVE MODULE, METHOD OF ASSEMBLING THE SAME, AND ELECTRONIC APPARATUS
摘要:
A drive module of the invention includes a tubular or columnar body to be driven, a tubular supporting body for receiving therein the body to be driven, a plate spring member for elastically holding the body to be driven so as to be movable in a specific direction with respect to the supporting body, and a driving device for driving the body to be driven in the specific direction against a restoring force of the plate spring member. The driving device includes a shape memory alloy wire engaged with the body to be driven and contracted by heat, which is generated when an electric current is applied thereto, to drive the body to be driven against the restoring force of the plate spring member, and a holding terminal having a wire holding portion for holding an end of the shape memory alloy wire. The holding terminal has a fitting portion positioned by being fitted to the supporting body, and a regulating portion serving as a detent of the supporting body. The holding terminal is supported by and fixed to the supporting body.
