PROBLEM TO BE SOLVED: To provide a boring device, with which a second hole intersecting a first hole at right angles can be easily bored in a wooden member under the state that the center of the second hole is nearly brought in line with the center of the first hole. SOLUTION: In a guide part 1, in which first guide rails 2 and 3 are opposite to each other with a predetermined intervals between them, a first planar member 6, a first slider, which moves a second planar member 8 by operating a first slider driving mechanism 9, and a second slider 12 having a dowel 14 are provided. In addition, to the second slider 12, a horizontally moving member 15, which can move horizontally normal to the axial directions of the first guide rails 2 and 3, is provided. A horizontal locking mechanism 18 for locking the horizontally moving member 15 is provided. A vertically movable member 24, which can move vertically to the horizontally moving member 15, is provided. At the same time, a vertically locking mechanism 27 for locking the vertically moving member 24 is provided. In the vertically moving member 24, a cylinder 30, the center line of which and the center line of the dowel 14 form a plane, is mounted. Second guide rails 31 and 32, which horizontally guide a third slider 33 so as to move the center of a retaining hole 34 along the extension of the center line of the cylinder 30, are provided in the vertically moving member 24.
