PROBLEM TO BE SOLVED: To provide a unit type wave gear device simple in structure, having a small number of parts and doing with simple assembling work. SOLUTION: This unit type wave gear device 1 has a unit case 2, a wave gear speed reducing mechanism 3 built therein, an input shaft 4 and an output shaft 5. The output shaft 5 is integrally formed on a boss 323 of a cup-like flexible external gear 32, and projected to the outside through a second end plate 5. The boss 323 is screwed on the second end plate 22, a cross roller bearing 6 is constituted between the outer peripheral surface of the boss and the inner peripheral surface of the unit case, the second end plate 22 is supported in the freely rotating state on the unit case 2 through the bearing. |
