Abstract
A coupling unit provides a coupling between a valve element of an opening-closing valve and a moving element of an electromagnetic actuator so as to enable mutual movement of the two elements relative to each other within a predetermined restricted range. Accordingly, it is possible to provide an opening-closing valve driving apparatus that can reduce power consumption of the electromagnetic actuator and is excellent in responsivity.
