PURPOSE:To make it possible to transmit power at any angle within about 180deg. so as to effect a turn of small radius by journalling an output side bevel gear meshed with an idle bevel gear, to an output side bevel gear support bolt which is journalled rotatably to an intermediate shaft. CONSTITUTION:An input shaft 1 is incorporated in an input side casing 3. An input shaft side bevel gear 4 is meshed with an idle bevel gear 7. An intermediate shaft 8 crosses orthogonal to the input shaft 1 and are inserted into intermediate brackets 10a, 10b. An output side bevel gear 13 is also meshed with an idle bevel gear 7, having an annular hub 14 rotatably supported to an output side bevel gear support bolt 15 through a bearing 16. Thus, adjustment may be made even over about 180deg. angle so as to effect a turn of small radius even though it has a power transmission mechanism using a plurality of bevel gears.
