Description
この場合、前記孔部は、前記円筒部の延出基端部まで達するように当該円筒部を内径側から外径側まで貫通させる構成とすればよい。また、前記孔部は、前記円筒部の延出基端部まで達するように当該円筒部を内径側から外径側まで貫通させるとともに、前記軌道平板部の外周縁部、もしくは内周縁部を軸方向に貫通させるように形成してもよい。
また、前記孔部は、軸方向に対して前記軌道面の形成側の孔周面が前記軌道平板部とは面一ではなく、これらの孔周面と軌道平板部の間に段差が介在されるように、前記円筒部を内径側から外径側まで貫通させる構成であってもよい。
In this case, the hole portion may be configured to penetrate the cylindrical portion from the inner diameter side to the outer diameter side so as to reach the extended base end portion of the cylindrical portion. Further, the hole portion penetrates the cylindrical portion from the inner diameter side to the outer diameter side so as to reach the extended base end portion of the cylindrical portion, and the outer peripheral edge portion or the inner peripheral edge portion of the track flat plate portion is pivoted. You may form so that it may penetrate in the direction.
In addition, the hole has a hole circumferential surface on the side where the raceway surface is formed is not flush with the track flat plate portion in the axial direction, and a step is interposed between the hole peripheral surface and the track flat plate portion. As described above, the cylindrical portion may be configured to penetrate from the inner diameter side to the outer diameter side.
