<P>PROBLEM TO BE SOLVED: To achieve both of the improvement of the accuracy of positioning of a first molded body and a second molded body and the improvement of reliability of the prevention of overflow of a brazing filler metal from the joined interface of both molded bodies by taking parts obtained by sintering and brazing the first molded body and the second molded body as the object of the improvement. <P>SOLUTION: A brazing filler metal pool part is provided on a sintered brazed joined parts, which is obtained by butting the first molded body and the second molded body in the axial direction to sinter them and by simultaneously performing the braze in joined surfaces. The brazing filler metal pool part 8 is formed by the space between a chamfered part 7 and an overflow groove 5, by providing the chamfered part 7 at the top of a projecting part 6, providing an overflow groove 5 in the corner part of a recessed part 3, arranging the end part P of the overflow groove 5 on the side of the joined surface from the end part Q of the chamfered part 7 and providing the gap of W=0.02-0.1 mm between the land corner part C of the chamfered part 7 and the side face 3b of the recessed part 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
