A cylindrical cutting edge 12 whose surface 11 is oblique with respect to the direction of propulsion is rotatably connected, and a pair of stoppers 13 and 13 are fixed to the inner peripheral wall of the cutting edge facing each other. An auger 14 is inserted into the inside of the blade mouth 12, and the tip of the auger shaft 15 is provided with a pair of levers 16 that interfere with the stopper 13.

During normal straight forward propulsion, as shown in FIG. 1, the auger 14 is moved forward to cause the tip surface 17a of the blade 17 to protrude further forward than the tip surface 11 of the blade mouth 12, so that the lever 16 and the stopper 13 do not interfere with each other. By rotating the auger 14 in this manner, it is propelled while excavating and discharging soil. At this time, in normal soil, the auger 14 and the pipe are propelled at the same time, but in particularly hard soil, the auger I4 is slid back and forth to sufficiently loosen the soil, and then the pipe is propelled.

When changing the propulsion direction by measuring the positional deviation in the propulsion direction using a special means such as a transit, first move the auger 14 backwards to cause the stopper 13 and lever 16 to interfere with each other, as shown in FIG. In this state, the auger 14 is rotated by a predetermined angle, and the cutting edge 12 is rotated by a predetermined angle, so that the tip end surface 11 of the blade is oriented in a direction corresponding to the desired direction of propulsion.
