<p>PURPOSE:To reduce the planar size of a space necessary to dispose a tilting lever and to shorten a driving system by rotatably supporting low and high speed tilting levers to one supporting shaft. CONSTITUTION:A low speed tilting lever 39 for supporting a low speed transmission gear 44 inserted between low speed transmission systems 13, 34 and a driving system 17, and a high speed tilting lever 51 for supporting a high speed transmission gear 57 inserted between high speed transmission systems 35, 38 and the system 17 are rotatably supported to one supporting shaft 29. Thus, since a planar size of a space necessary to dispose the two levers 39 51 may be small and the gear of output stage for outputting the rotation of the system 17 to the gears 44, 57 may be a common one for the two transmission gears, the structure of the system 17 may be simplified and its system can be shortened.</p> |
