Abstract: An outer-ring lubricating groove pattern (6) formed in an outer-ring raceway surface (47a) and an inner-ring lubricating groove pattern (5) formed in an inner-ring raceway surface (46a) of a wave generator bearing (45) of a strain wave gearing device (1) are patterns in which linear lubricating grooves (53, 54, 60) having very small widths and depths of several micrometers or less are arranged at fine pitches of several micrometers or less. The inner-ring lubricating groove pattern (5) includes a second groove pattern (52) formed in major-axis-side inner-ring raceway surface portions (46B1, 46B2) to hold the lubricant, and a first groove pattern (51) formed in minor-axis-side inner-ring raceway surface portions (46A1, 46A2) to hold the lubricant and guide the lubricant to the second groove pattern (52). This configuration improves the contact state between balls (48) and the inner-ring and outer-ring raceway surfaces (46a, 47a) of the wave generator bearing (45), thus reducing the coefficient of friction therebetween.
