Document Type and Number:
Japanese Patent JP2019157679
Kind Code:
A
Abstract:
To provide a valve opening/closing timing controller capable of preventing occurrence of contact noise at an engagement portion of a joint member.SOLUTION: A valve opening/closing timing controller comprises an internal gear type output gear 25 enclosed in a drive side rotor A, and an external gear type input gear 30 partially meshed with the output gear 25, wherein a differential speed reduction mechanism is configured so that the output gear 25 autorotates about an eccentric shaft core Y and revolves about a rotational shaft core X by driving force of an electric actuator M. A linkage mechanism linking the drive side rotor A and the input gear 30 comprises a joint member 40, and comprises energization members 35 and 36 that suppress positional displacement of the joint member 40.SELECTED DRAWING: Figure 1
