PROBLEM TO BE SOLVED: To accurately manufacture a large transmissible power shaft coupling of a type transmitting power via a rolling element arranged at a crossing position of guide grooves perpendicularly crossing between parallel two shafts at low cost. SOLUTION: A plurality of the guide grooves 9, 10 are provided on opposing surfaces of opposing two plates 4, 5 to perpendicularly cross a guide groove at a position corresponding to a mating plate. A plurality of sub couplings 3 capable of independently transmitting power between parallel two shafts via a steel ball 6 arranged at the crossing position of the guide grooves 9, 10 are arranged between two rotary members 1, 2 having parallel rotary shafts. Necessary transmissible power can be obtained by changing number of the sub couplings 3. Consequently, even large transmissible power coupling can be accurately manufactured at low cost by using a small size sub coupling parts. COPYRIGHT: (C)2006,JPO&NCIPI
