Abstract:
This exhaust cam shaft ( 2 ) is provided with a shaft part ( 5 ) and cam parts ( 6  to  13 ) provided on the outer circumference of the shaft part ( 5 ). The shaft part ( 5 ) has holes ( 16, 17, 19 ) opened at predetermined positions on the outer circumferential surface of the shaft part ( 5 ). The holes ( 16, 17, 19 ) are formed so as to be gradually tapered from an outside of the shaft part ( 5 ) toward a center of the shaft part ( 5 ) in a radial direction.

Claim (Index 8):
A method for manufacturing the cam shaft for an engine according to  claim 1 , the method comprising the steps of:\n preparing a pattern of the cam shaft, the pattern including a first pattern element corresponding to a one-side portion of the cam shaft in a radial direction and a second pattern element corresponding to an another-side portion of the cam shaft in the radial direction; manufacturing a first sand mold by placing the first pattern element in a casting flask, charging casting sand into the casting flask, hardening the casting sand, and taking the first pattern element out of the casting sand having been hardened; manufacturing a second sand mold by placing the second pattern element in a casting flask, charging casting sand into the casting flask, hardening the casting sand, and taking the second pattern element out of the casting sand having been hardened; manufacturing a casting mold by combining the first sand mold and the second sand mold to each other, the casting mold having a cavity in which the cam shaft is to be casted; pouring a molten metal into the cavity and cooling down the molten metal to harden the molten metal; and taking the cam shaft out of the casting mold by causing the casting mold to collapse and removing the casting mold.
