Abstract
A valve timing control device for an internal combustion engine, comprises a drive rotary member rotated by a crankshaft of the engine, a driven rotary member to rotate a camshaft of the engine upon rotation of the drive rotary member; a rotational phase control mechanism having an intermediate rotary member rotated relative to the drive and driven rotary members to cause relative rotation between the drive and driven rotary members and an braking mechanism having a hysteresis brake that generates a braking force to cause the intermediate rotary member to rotate relative to the drive and driven rotary members.
