Abstract
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.
