Abstract
A working machine includes: a machine body; an operator's seat; an operation device to pivot on a pivot shaft that extends in a width direction; and a working device to be operated using the operation device. The operation device includes an operation lever and a control valve to be operated using the operation lever and connected to hydraulic hoses. The control valve includes a valve member to be actuated by operating the operation lever, and a block containing fluid passages through which fluid selectively flows upon actuation of the valve member. The fluid passages bend such that first ports in an upper surface of the block facing the valve member and second ports in a peripheral surface extending from a periphery of the upper surface are in communication with each other. The hydraulic hoses are connected to the second ports and extend in a direction away from the peripheral surface.
