摘要： PROBLEM TO BE SOLVED: To miniaturize and lighten a driving device by rotatably installing a plurality of circular cutter heads connected in a manner that the cutter heads can be synchronized and driven at the front end section of an excavator body and driving and rotating the cutter heads. SOLUTION: Three circular cutter heads, on which cutter bits are fixed, are juxtaposed in the front section of a cylindrical excavator body 11, in which three cylinders are communicated in the radial direction, so as to be mutually superposed. Hydraulic jacks 28, 29 are expanded and contracted and driven, and the cutter bits unified with each revolution body 21, 22, 23 are reciprocated and rotated through connecting rods 24, 25. This tunnel excavator is moved forward by elongating shield jacks and the forward ground is excavated by the cutter bits at that time, thus forming a tunnel. Accordingly, a plurality of the cutter heads can be turned and driven by one driving means, and device itself can be miniaturized and cost reduced.
