Driving mechanism, driving device, and lens driving device |
摘要 |
A driving mechanism, a driving device, and a lens driving device includes a lever member. The lever member includes an arm portion for surrounding a part of a driven member in a side direction. The arm portion has a plurality of displacement output portions to be engaged with the driven member. The lever member is constructed in such a manner that a displacement amount of the displacement output portions in a predetermined first axis direction is set larger than a displacement amount of a displacement input portion to be generated by input of a moving force to be applied by a shape memory alloy actuator. The driving mechanism, the driving device, and the lens driving device enable to obtain a large displacement amount with a reduced size and a reduced weight, and stably move the driven member.
