To provide a drum operation lever lock device which solves the problem that when a concrete mixer truck travels while loading ready-mixed concrete, in order to prevent the ready-mixed concrete from adhering to a drum, the concrete mixer truck travels while rotating a drum at low speed with an operation lever at a stirring position, but the operation lever results in moving to a reverse position due to vibration during traveling of the concrete mixer truck and abutment of the operation lever on street trees, and ready-mixed concrete results in discharging onto a road during traveling, the drum operation lever lock device capable of avoiding such inconvenience and preventing the operation lever from moving to a reverse position.SOLUTION: A drum operation lever lock device of a cement mixer truck has an engagement recess on one end of a plate material, and has a hook-shaped member on the other end thereof.SELECTED DRAWING: Figure 1

    【課題】コンクリートミキサー車が生コンを積載して走行する際には、生コンがドラム内で固着するのを防ぐため、操作レバーを攪拌位置にしてドラムを低速で回転させながら走行しているが、コンクリートミキサー車の走行中の振動や街路樹に操作レバーが当たったりして、操作レバーが逆転位置に移動してしまい、走行中に生コンを路上に排出してしまうことがあった。本発明はかかる不都合を回避可能な操作レバーが逆転位置に移動するのを阻止するドラム操作レバーロック装置を提供することを目的とする。【解決手段】本発明に係るコンクリートミキサー車のドラム操作レバーロック装置は、板材の一方端に係止凹部を他方端に鉤状部材を設けて構成した。【選択図】 図1
