Abstract

A valve timing adjustment device includes a sprocket, a vane rotor and a shim. The sprocket is configured to rotate. The vane rotor is received in the sprocket such that the vane rotor is rotatable relative to the sprocket. The vane rotor includes a supply oil passage that is configured to communicate with an external oil passage, and a rotational phase of the sprocket is changed when the vane rotor is rotated relative to the sprocket. The filter is configured to filter hydraulic oil, which is conducted in a connection oil passage that is configured to connect between the external oil passage and the supply oil passage. The shim is placed between the driven shaft and the filter.
