Abstract

A variable valve timing control apparatus (100) includes a driving-side rotating member (3), an driven-side rotating member (5), a cam shaft (8), a control valve (124) switching supply and discharge of a working fluid relative to an advanced angle chamber (6a) and a retarded angle chamber (6b), an advanced angle-side oil passage (42), a retarded angle-side oil passage (43), a spider (23b) provided with a first oil passage (82) and a second oil passage (83), a seal mechanism (29) partitioning between at least one of the first oil passage and the second oil passage, and an outside space (110), and the seal mechanism allows air to come in the at least one of the first oil passage and the second oil passage in a case where pressure inside the at least the one of the first oil passage and the second oil passage is lower than air pressure of the outside space.
