The invention provides a mechanical component and a timepiece using the same, can improve fixing force and rotary inhibiting force of a rotary member relative to an axle member, and can enable loss ofrotation torque to be relatively small and endurance to deformation caused by external stress to be relatively high. The escape wheel (35) serving as a mechanical component is characterized by havingan axle member (102), and an escape pinion portion (101) serving as a rotary member and having a holding portion (115) which holds the axle member (102), and a rim portion (111) which has a pluralityof tooth portions (112). The holding portion (115) has a first holding portion (113) which extends from the rim portion (111), and a second holding portion (114) which is disposed by being branched from the first holding portion (113).
