Abstract
An operating device with an operating lever for a control valve includes: an input member connected to the operating lever; an output member connected to a slide spool of the control valve; and a swing link for relaying a displacement of the input member to the output member. The swing link is swingable about a swing shaft center on one end and is connected to the input and output members. A latch portion in the swing link is farther than a connecting point with the output member from the swing shaft center. A lock body is switchably operable between a lock position and a release position, and at the lock position, engaged with the latch portion at a neutral position to limit a swing of the swing link about the swing shaft center by which the control valve is locked at a neutral state.
