Title:

VALVE TIMING ADJUSTMENT DEVICE, AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2018/101059

Kind Code:

A1

Abstract:

A friction member (25, 95, 101, 111) is provided in such a manner as to be sandwiched between a driven shaft (13) of an internal combustion engine and a vane rotor (22, 94, 122), and has an oil passage hole (68) for making a first oil passage (15) of the driven shaft (13) and a second oil passage (52) of the vane rotor (22, 94, 122) communicate with each other. A positioning portion (82, 91, 116) comprises a first engaging portion (71, 92, 112) of the vane rotor (22, 94, 122), and a second engaging portion (73, 93, 114, 115) of the friction member (25, 95, 101, 111). The positioning portion (82, 91, 116) regulates relative rotation between the vane rotor (22, 94, 122) and the friction member (25, 95, 101, 111) while keeping the communication between the first oil passage (15) and the second oil passage (52) established by the oil passage hole (68).
