<P>PROBLEM TO BE SOLVED: To provide a connection structure of a rotary shaft capable of surely preventing a connection part from coming off with more simple structure in a connection structure of the rotary shaft concentrically connecting projection shape rotary shafts by inserting the same in a recess shape rotary shaft. <P>SOLUTION: A part of the projection side connection part 10a is formed in a column shape or a polygon column shape, and a projection side lock groove M1 is formed in an outer circumference direction of a part of the cylindrical shape or the polygon shape. A part of the recess side connection part 30a is formed in a column shape space or a polygon column shape space to be fitted with the column shape or the polygon column shape part of the projection side connection part, and a recess side lock groove M2 is formed on an inner circumference direction at a position opposing to the projection side lock groove M1. A connection medium (C ring R2 or the like) is put in a lock space formed by a projection side lock groove M1 and the recess side lock groove M2 when the projection side connection part 10a and the recess side connection part 30a are fitted. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
