To prevent, with a simple structure, deformation such as a twist of an actuator at the time of moving operation and easily check the operation state of an actuator to easily and reliably establish an electrical connection, inclined surface parts are provided at both end portions in a longitudinal direction in end faces on a rotational radial outer side of the actuator pinching or freeing a signal transmission medium to approximately uniformly act an entire pressing force of an operator over a full length of the actuator. With this, a situation that the actuator is pressed as being twisted is eliminated to achieve an excellent action of pinching the signal transmission medium and an easy and reliable visual check of the state of rotation of the actuator. |
