<P>PROBLEM TO BE SOLVED: To provide a manual winding wheel train enabling setting of a winding-up torque below a desired level at a movement itself, a timepiece movement having the wheel train and a timepiece having the movement. <P>SOLUTION: A manual winding wheel train 1 is provided for a movement 2 of a timepiece 3. The manual winding wheel train 1 comprises a plurality of gears 60, 70, 41, 42 mutually engaged to transmit gyration of a winding stem 20 to a square hole wheel 37; an input side member 60 having an input side friction engagement portion 67 (H1) and an output side member 70 having an output side friction engagement portion 72 (H2), facing each other at the friction engagement portions 67, 72, and friction-engaging with each other at the portions facing each other; and elastic means 80 that presses one friction engagement portion 72 to another friction engagement portion 67. <P>COPYRIGHT: (C)2012,JPO&INPIT |
