摘要： There is provided a connection structure between a hollow output shaft of a speed reducer, which is provided with the hollow output shaft including a hollow portion, and a driven shaft of a counterpart machine inserted into the hollow portion of the hollow output shaft. The connection structure includes a communication passage through which the hollow portion of the hollow output shaft communicates with an internal space of the speed reducer. A space, which includes clearance between the hollow output shaft and the driven shaft, is formed as a closed space.

摘要： A supporting structure includes a casing, a bearing having an inner ring, an outer ring, and rolling elements disposed between the inner ring and the outer ring, and an attachment member which detachably and directly attaches a shaft to the inner ring. The outer ring is supported by the casing, and the shaft is adapted to be able to be directly fixed to or removed from the inner ring by the attachment member in a state where the bearing is assembled to the casing.
