PROBLEM TO BE SOLVED: To provide a lining device for tunnel capable of performing prompt traveling between a lining process and a process before and behind the process without having any interference with other working machines in a small cross- section, and of attaining highly efficient work. SOLUTION: A projection lining material obtained by kneading a lining material with an accelerating agent is projected in the diametrical direction from the central position of a tunnel, and a body 1 forming a lining layer in a circular-arc shape in a tunnel wall surface is supported through an inclining arm 4 on a frame 2 having a storage space for other working machines at its central part. Its inclining arm is connected to a slider 3 mounted on a frame so as to move fore and aft. In the case of use, the slider is moved forward to dispose a main body at the central position of the tunnel by an inclination arm protruding forward from the front surface of the frame. In the case of no use, the slider is moved backward to shelter the body to the tunnel wall surface side near the frame.
