Abstract: [Means for Solution] A gear member includes a tooth having a tooth flank whose profile is an involute curve, wherein in a cross-section of the tooth perpendicular to a face width direction, the tooth has a depression, near a top land, hollowed in the tooth flank relative to the involute curve.

Abstract: A joined component includes a first member provided with a first joint surface having an arranging part where a brazing filler material is arranged, a second member joined to the first member by brazing, and provided with a second joint surface having an accommodating recess that opposes the arranging part, a guide groove formed in the first joint surface or the second joint surface, and extending from the arranging part or the accommodating recess toward a fringe of the first joint surface or the second joint surface, and a chamfer formed along the fringe of the first joint surface or the second joint surface, and the guide groove communicates to the chamfer.

Abstract: It is an object of the present invention to effectively suppress the overflow of brazing material from each joint of a sinter-brazed component, such as a planetary carrier, obtained by brazing a plurality of members together. According to the present invention, there is provided a sinter-brazed component obtained by mating and joining a first member having a first bonding surface and a second member having a second bonding surface to each other. Brazing material is provided between the first bonding surface and the second bonding surface. The first bonding surface has a first recess, the first recess having an inner peripheral wall and a bottom surface. The inner peripheral wall extends along and on an inner side of a profile line of the first bonding surface.
