PROBLEM TO BE SOLVED: To provide a power transmission device capable of avoiding interference with other members and, moreover, surely preventing deviation in the support shaft axial direction of a stabilizer even when vibrations become large.;SOLUTION: An annular projection part 21 is disposed on a position corresponding to the center of the stabilizer for the support shaft 7 and a recessed part 22 which fits into the annular projection part 21 is disposed on the center part in the length direction of holding walls 12 holding the stabilizer 6. [a distance between a height position H1 of the center parts of the holding walls 12 and a tip end positions B1 of the annular projection part 21, at a part facing the holding walls] can be set to be larger than [a distance between a height position H2 of the outer end parts of the holding walls 12 and a tip end position B1 of the annular projection part 21, at a part facing the holding walls]. Accordingly, when the stabilizer 6 is vibrated and the relative position of the support shaft 7 with respect to the stabilizer 6 is changed, a part having a height H1 of the holding walls 12 can be surely prevented from getting over the annular projection part 21.;COPYRIGHT: (C)2012,JPO&INPIT
