<P>PROBLEM TO BE SOLVED: To provide a bearing unit for a timepiece, a movement and the timepiece, in which an inter-pitch distance of a sphere can be held at a fixed value, collision on a shaft or an outer wheel of a holder can be reduced and bearing loss variation can be reduced by reducing an inclination in a longitudinal direction of a center axis of the holder from the longitudinal direction of a center axis of a shaft body or the outer wheel. <P>SOLUTION: A holder 201a is guided by a shaft body 143 or an outer wheel 185 by forming a third guide face 207a on a third inner peripheral surface 204 and abutting the third guide face 207a on a second outer peripheral surface 208 of a small-diameter shaft part 147. <P>COPYRIGHT: (C)2013,JPO&INPIT |
