Abstract
A hollow-type strain wave gearing unit () has a sealing member () for sealing a gap () opening to the inner peripheral surface of a unit hollow portion () passing through in an axis () direction. The gap () includes a gap section () between an outer peripheral side end race () on the wave generator side and a boss side end face (), both faces opposing each other in the axis () direction, and the sealing member () is assembled therein. The gap section () is formed in a state partially entering the inside of the inner ring () of the second bearing () supporting the wave generator (). It is possible to realize a hollow-type strain wave gearing unit with a sealing mechanism that is suitable for increasing the inner diameter of the unit hollow portion and for reducing the unit axial length.
