<p>Each end of the flexible gear coupling has a seal member (14) axially slidably disposed on the outer circumference surface of a connection portion (13b) of a pinion (13). The seal member (14) has a spherical seal surface (14a) of predetermined radius (r) having its center at the position (A) at which the center-line (A1) of the width of an outer teeth gear (13a) of the pinion (13) crosses the axis (A2) and abutting with a corresponding surface (15a) of an end cover 15. A spring (17) on the connection portion (13b) of the pinion (13) urges the seal member (14) against the abutting surface (15a) of the end cover (15) <IMAGE></p> |
