A method for manufacturing a spline telescopic shaft according to the present invention includes a toothless portion forming step (S2) of forming a toothless portion in one of an external tooth of a shaft body (40) and an internal tooth of a tubular body, a resin layer forming step (S3) of forming a resin layer (50) by arranging one of the shaft body (40) and the tubular body in a mold including acavity and injecting a resin into the cavity, the cavity being included in a flat receiving surface that faces tooth flanks of one of the external tooth of the shaft body (40) and the internal toothof the tubular body, and a cooling step (S4) of cooling one of the shaft body (40) including the resin layer (50) and the tubular body including the resin layer (50) to form a lubricant reservoir (52)in the resin layer (50).

    本发明涉及用于制造花键伸缩轴的方法以及花键伸缩轴。根据本发明的用于制造花键伸缩轴的方法包括缺齿部形成步骤(S2)、树脂层形成步骤(S3)以及冷却步骤(S4),其中,缺齿部形成步骤(S2)是在轴本体(40)的外齿和管状本体的内齿中的一者中形成缺齿部,树脂层形成步骤(S3)是通过将轴本体(40)和管状本体中的一者布置在包括腔的模具中并将树脂注射到腔中来形成树脂层(50),该腔包括于平坦的接纳表面中,该平坦的接纳表面面向轴本体(40)的外齿和管状本体的内齿中的一者的齿面,冷却步骤(S4)是对包括树脂层(50)的轴本体(40)和包括树脂层(50)的管状本体中的一者进行冷却以在树脂层(50)中形成润滑剂储存部(52)。
