Document Type and Number:
Japanese Patent JP2011211781
Kind Code:
A
Abstract:
To provide a coupling device coupling a movable piece and a stator and elastically supporting the movable piece so that it can be reciprocated in a thrust direction, wherein it is possible to reduce the influence of resonance, prevent or suppress breakage and wear in a blade spring, and carry out desired functions.
The coupling device 5 includes the blade spring, couples the movable piece 3 and the stator 2 with each other, and elastically supports the movable piece 3 so that it can be reciprocated in the thrust direction A.
