<p>PURPOSE:To separate a sliding mechanism section for a main handle from an electric system for a deadman switch by moving a push plate in the direction orthogonal to the sliding direction of the main handle while being interlocked with the rotational or push-in operation of the main handle and operating the deadman switch. CONSTITUTION:When a grip section 29 for a main handle 27 is gripped and turned and operated in the clockwise direction against the force of a torsional spring 37, a push plate 32 is slid in the left direction by a cam 34. A roller 45 is pushed by the sliding of the push plate 32 and a lever 44 is rotated in the clockwise direction, and an operating lever 43 for a deadman switch 40 is pushed in. Consequently, the stoppage of a car by the deadman switch 40 is released, and the state enabling power-running braking operation by the sliding operation of the main handle 27 is brought. Accordingly, leads drawn around a mechanism section in a fixing frame body can be removed.</p> |
