<P>PROBLEM TO BE SOLVED: To realize with ease a storage of a driving device for a construction machine rotation mechanism including an electric motor within the construction machine compactly with avoiding interference with other equipment. <P>SOLUTION: In a driving device for a construction machine rotation mechanism, a pinion 12 meshes with a ring gear 104 fixed to a lower body 101. Rotational driving force of an electric motor 11 fixed to an upper rotating body 102 is outputted from an output shaft 13 and is then inputted to an input shaft 14. A speed reduction part 16 is connected to the input shaft 14 and an output part 15 to which the pinion 12 is fixed. The rotational driving force inputted to the input shaft 14 is reduced its rotational speed to be transmitted and is then outputted to the output part 15. An input position changing unit 17 is capable of transmitting the rotational driving force from the output shaft 13 to the input shaft 14. The input position changing unit 17 is provided between the output shaft 13 and the input shaft 14 both arranged in such a manner that an axial direction C1 of the output shaft 13 and an axial direction C2 of the input shaft 14 are parallel to each other, thereby changes a position of an axial direction of the rotational driving force at inputting the rotational driving force outputted from the output shaft 13 to the input shaft 14. <P>COPYRIGHT: (C)2012,JPO&INPIT |
