Valve timing variation device

Abstract

Since the conventionally the chip seal 14, 16 and the metallic blade spring 15, 17 have been formed separately, assembly efficiency has been poor (for example when the chip seal 14, 16 is inserted, the metallic blade spring 15, 17 detaches and falls out) which lowers productivity. As a result, the cross sectional shape of the chip seal 21 which pushes against the rotor 13 is made in the shape of a letter L.
