VALVE TIMING ADJUSTING DEVICE, APPARATUS FOR MANUFACTURING SAME AND METHOD FOR MANUFACTURING SAME

摘要

A valve timing adjusting device for and engine includes a sprocket configured to rotate by receiving drive power from a driving shaft, a vane rotor fixed to a driven shaft so as to be rotatable relative to the sprocket, a housing that includes an oil chamber housing the vane rotor and is fixed to one end in a thickness direction of the sprocket, a bolt fixing the sprocket to the housing, and a knock pin inserted into a sprocket hole formed in the sprocket at one end thereof and into a housing hole formed in the housing at the other end thereof to restrict relative relation between the sprocket and the housing. The knock pin abuts against an inner wall of the sprocket hole at one end thereof, and abuts against an inner wall of the housing hole at the other end thereof.

1. A valve timing adjusting device for adjusting open/close timing of an intake valve or an exhaust valve driven by a driven shaft of an engine by varying a rotational phase between the driven shaft and a driving shaft of the engine, comprising:
a sprocket configured to rotate by receiving drive power from the driving shaft; a vane rotor fixed to the driven shaft so as to be rotatable relative to the sprocket; a housing that includes an oil chamber housing the vane rotor, the housing being fixed to one end in a thickness direction of the sprocket; a bolt fixing the sprocket to the housing; and a knock pin inserted into a sprocket hole formed in the sprocket at one end thereof and into a housing hole formed in the housing at the other end thereof to restrict relative relation between the sprocket and the housing; wherein, when a direction to which the vane rotor is phase-controlled when starting the engine is referred to as a first direction, and a direction opposite to the first direction is referred to as a second direction, the knock pin abuts against an inner wall in the first direction of the sprocket hole at one end thereof, and abuts against an inner wall in the second direction of the housing hole at the other end thereof.
