Abstract: The wave generator of the strain wave gear device comprises: a rigid plug; a roller bearing fitted on the elliptical outer circumferential surface thereof; and first and second cylindrical springs, which press loose rollers that have some play in the radial direction between the outer race and the inner race of the roller bearing against the outer raceway surface. The loose rollers are pressed against the outer raceway surface with a linear contact and roll according to the outer raceway surface. Skewing of the rollers is limited, ensuring smooth rotation of the roller bearing.
