VALVE TIMING REGULATOR

WIPO Patent Application WO/2020/045594

A1

A second rotational solid (40) has an opposing surface (401) that opposes a shaft-end surface (161) of a driven shaft (4). A friction shim (50) is provided between the opposing surface (401) and the shaft-end surface (161), and has a first shim contact surface (501) capable of coming into contact with the shaft-end surface (161), and a second shim contact surface (502) capable of coming into contact with the opposing surface (401). After being attached to the driven shaft (4) of a valve timing regulator (1), the friction shim (50) causes frictional force between the first shim contact surface (501) and the shaft-end surface (161), and also between the second shim contact surface (502) and the opposing surface (401). A contact member (60) has a first member contact surface (601) capable of coming into contact with the shaft-end surface (161). The contact member (60) is provided to the second rotational solid (40) so that when the contact member (60) is attached to the driven shaft (4) of the valve timing regulator (1), the first member contact surface (601) comes into contact with the shaft-end surface (161) before the first shim contact surface (501) comes into contact with the shaft-end surface (161).
