PROBLEM TO BE SOLVED: To realize a structure miniaturized lightening weight, by simplifying the structure further with a space contracted between a pair of the fellow output side disks. SOLUTION: A sleeve 25a supporting a pair of output side disks 4, 4 is supported to a support plate 34 by a first rolling bearing 37 which is an angular type ball bearing. An end part of a rear half part 16b constituting an input shaft 16 is supported to a wall part 41 of a casing 15a by a second rolling bearing 42 which is also an angular type ball bearing. A direction of contact angleα,βof the first/second rolling bearing 37, 42 is set to a reverse to each other. A thrust load, generated when positive direction torque is transmitted, is supported by the first rolling bearing 37, a thrust load, generated when negative direction torque is transmitted, is supported by the second rolling bearing 42.
