Claims

[Scope of utility model registration request]

In a system in which the rotational force of the crankshaft is transmitted to the camshaft for opening and closing the intake valves through a pair of transmission members such as pulleys, sprockets, or gears supported by both shafts, at least one of the transmission members is an adductor fixed to the shaft;
an abductor body disposed with a membrane aligned with the axle of the abductor body; an elastic body connecting the abductor body to the adductor body so as to be elastically movable in the circumferential direction; 1. A valve train for an engine, comprising a stopper that restricts free movement relative to a rolling element within a required angular range.
