PURPOSE: To provide an end part member for rotating driving body which can surely transmit a driving force without subjecting the rotating driving body to a complicated work. CONSTITUTION: An end part member 1 is formed of a hollow cylindrical sintered body having a high density part S1 on one side end part and a high density part S3 in the middle part. A tooth body part 2 which is a driving force transmitting part is provided on the high density part S1 side end part, and a through-hole 3 which is a locking pin mounting hole for a rotating drum 9 which is a rotating driving body to be fitted to the end part member 1 is provided on the high density part S3 in the middle part. Thus, only by forming a notch part 91 capable of being engaged with the locking pin on the top end part of the rotating drum 9, and pressing the locking pin into it, a driving force can be surely transmitted. Since the formation of a key groove on the rotating drum 9 is dispensed with, the working is facilitated. |
