いることを特徴とする可変バルブタイミング機構。A cam piece 12 having at least two driving cams 13a, 13b with different cam profiles for one opening/closing valve 3 is arranged on a cam shaft so that it can be moved in the axial direction via a pawl slide bearing 20, but not in the rotational direction. In the variable Hartz timing mechanism for an internal combustion engine, the at least two drive cams are selectively switched to operate an on-off valve by moving the cam piece 12 in the axial direction.
The plurality of axial balls provided on the inner surface of the camshaft 10 and the outer surface of the camshaft 10 are laser-burned at least in areas A, B, C, and D that contact the balls 21 of the slide bearing 20. A variable valve timing mechanism characterized by a variable valve timing mechanism.
