To provide a spherical body driving device that can suppress stress concentration from occurring to enhance fatigue strength.SOLUTION: A spherical body driving device 10 comprises a spherical body 17 in which a first opening part 81 and a second opening part 82 which are point-symmetric with a center point O are formed. The spherical body 17 rotates with a first rotary axis line 50 including the center point O, a second rotary axis line 70 and a third rotary axis line 90 as centers. The first rotary axis line 50 is parallel to a ground contact surface of the spherical body 17 and an X0 axial direction. The second rotary axis line 70 crosses the first rotary axis line 50 at a first eccentric angle β, at the center point O. The third rotary axis line 90 crosses the second rotary axis line 70 at a second eccentric angle α, at the center point O. An angle of the sum of the first eccentric angle β and the second eccentric angle α is an acute angle.SELECTED DRAWING: Figure 4

    【課題】応力集中が生じることを抑制して、疲労強度を向上させることが可能な球体駆動装置を提供する。【解決手段】球体駆動装置10は、中心点Oに対して点対称の第1開口部81及び第2開口部82が形成された球体17を備える。球体17は、中心点Oを含む第1回転軸線50、第2回転軸線70及び第3回転軸線90の各々を中心として回転する。第1回転軸線50は、球体17の接地面及びX0軸方向に平行である。第2回転軸線70は、中心点Oにて第1回転軸線50に第1偏心角度βで交差する。第3回転軸線90は、中心点Oにて第2回転軸線70に第2偏心角度αで交差する。第1偏心角度β及び第2偏心角度αの和の角度は鋭角である。【選択図】図4
