摘要： PROBLEM TO BE SOLVED: To provide a coupling device capable of simply carrying out joint work, ensuring joint strength and having nice-looking appearance in the case of coupling. SOLUTION: A woody member coupling device is so constituted that the head section 3 is formed by providing narrow diameter sections 2 to both end parts and that it is equipped with a shaft 1 with the inside walls of the narrow diameter sections 2 as the slopes 2s. At the same time, interlocking grooves 12 inserting the narrow diameter sections 2 into them are provided from one end to the other end, and it is equipped with cylindrical wedge members 11 for gradually increasing the thickness in both end parts of the interlocking grooves 12 contacted with the head section 3 from one end to the other end and collars 31 freely fitting to the insides of the narrow diameter sections 2 and expanding the circumferential walls by pushing against the slopes 2s with the wedge members 11.

摘要： PROBLEM TO BE SOLVED: To provide a fastening device facilitating the connecting work, having a high connecting strength, and being invisible from the outside so as to improve a respectable appearance. SOLUTION: This fastening device is provided with a pair of spherical nuts 11 and 12 having tooth shapes on their opposite surfaces, fastening device body 13 rotatably supporting them respectively, and a fastening bolt 14 having a male screw part 14a and a key groove 14b in the longitudinal direction in the outer circumference. The male screw part 14a of the fastening bolt 14 is threadly engaged with a female screw of the spherical nut 11, a key of the spherical nut 12 is inserted into the key groove of the fastening bolt 14, and the fastening bolt 14 is disposed orthogonally to the fastening device body 13 so as to be embedded in a first member. The fastening bolt 14 is rotated and moved axially by a first bit geared with the tooth shapes of the both spherical nuts, the tip part is geared with a receiver nut fixed to a second member, rotated reversely to the first bit by a second bit 20 rotating the spherical nut 11 alone so that the first member and the second member are tensioned and fastened.

摘要： 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.
