  • Valve opening-closing timing control apparatus
    Patent number: 11313256
    Abstract: An Oldham coupling includes an engagement arm. At least either a driving-side rotor or an input gear has an engagement portion engaged with the engagement arm and is connected to the Oldham coupling. The engagement arm has a pair of arm flat surface portions perpendicular to a rotational direction of the driving-side rotor. The engagement portion has a pair of engagement flat surface portions that the arm flat surface portions face in a sliding contact manner. Each arm flat surface portion is, within a range where the arm flat surface portion slides against a facing engagement flat surface portion, always in contact with an overlapping portion of the engagement flat surface portion with the arm flat surface portion when viewed from a direction perpendicular to a sliding direction of the Oldham coupling and in which the arm flat surface portion and the engagement flat surface portion overlap each other.
