    摘要: To provide a mechanical component, a mechanical component manufacturing method, a movement, and a timepiece allowing the forcing-in portion to be firmly fixed to the shaft member, providing a sufficient buffer effect, and capable of precisely determining the outer diameter dimension. Provided is a mechanical component rotating around a shaft member. This mechanical component includes: a component main body having a through-hole through which the shaft member is passed; and a forcing-in portion formed on the inner surface of the through-hole and fixed to the shaft member through the forcing-in of the shaft member. The component main body has a retaining recess constituting an anchor structure regulating displacement of the forcing-in portion with respect to the component main body. The forcing-in portion is formed of a metal material.

    摘要: The timepiece mechanism comprises a rotating wheel set, a support element, a pivoting member mounted on the support element and magnetic return means for returning one portion of the pivoting member against a surface of the rotating wheel set. The return means comprise a first magnet carried by the pivoting member and a second magnet carried by the support element. The first and second magnets are arranged such that, in normal operation, the interaction of their respective magnetic fields generates a magnetic force oriented to return said pivoting member portion towards said rotating wheel surface. At least one of the first and second magnets is arranged to permit reversal of its polarity, preferably with the aid of a tool, and thereby of the direction of the magnetic force acting on the pivoting member, said magnetic force then tending to move said pivoting member portion away from said rotating wheel set surface, which makes it easy to handle the various elements of the timepiece mechanism.
