PROBLEM TO BE SOLVED: To provide a power transmission structure capable of coping with a three-dimensional displacement of a transmission shaft and a transmitted shaft and a bearing structure. SOLUTION: This power transmission structure is characterized in that either one side of a connection portion between the transmission shaft and the transmitted shaft is formed in a generally spherical projected part and the other side is formed in a generally spherical support part slidably supporting the projected part, a slider is held on the support part at a specified position, a linear long groove allowing the slider therein at a position corresponding to the slider is provided in the projected part, and the transmission shaft and the transmitted shaft are connected to each other so as to be three-dimensionally displaced so that a power can be transmitted. This bearing structure is also formed in the same structure. COPYRIGHT: (C)2004,JPO
