Abstract:
1. An operating device with an operating lever for operating a control valve connected to an actuator comprising: an input member to which an operational displacement of the operating lever is transmitted; an output member connected to a slide spool of the control valve; a swing link configured to relay a displacement of the input member to the output member, the swing link being swingable about a swing shaft center defined on one end of the swing link, the swing link comprising: a lock body slidably operable between a lock position and a release position, the lock body being configured as a sliding body slidably guided between the lock position and the release position by a guide, wherein the lock body has a plate portion having a lock hole defined therein to receive the latch portion; the extension is bent at the intermediate portion and oriented toward an opening of the lock hole in a direction perpendicular to the opening; a swing motion of the swing link about the swing shaft center is limited by engaging the latch portion of the swing link at a neutral position with the lock hole defined in the lock body having slid to the lock position, and the control valve is locked to a neutral state; and the limitation to the swing motion of the swing link is cancelled by disengaging the latch portion from the lock hole after the lock body is operated to the release position, and the control valve is unlocked from the neutral state.
