To provide a planetary roller screw-type linear motion mechanism which facilitates automation of work for assembling a roller shaft of a planetary roller onto a carrier.SOLUTION: A width dimension of a second long hole 32 is greater than a width dimension of a first long hole 31. A first whirl-stop shaped part 46 and a first partial cylinder face 47 are formed on an external periphery of a first end part 16 of a roller shaft 15. The roller shaft 15 is whirl-stopped from revolving by the engagement of the first whirl-stop shaped part 46 and a longitudinal face 45 of the first long hole 31. A second whirl-stop shaped part 49 and a second partial cylinder face 50 are formed on an external periphery of a second end part 17 of the roller shaft 15, and only the second partial cylinder face 50 makes contacts with and supported on a longitudinal face 48 of the second long hole 32.SELECTED DRAWING: Figure 2

    【課題】遊星ローラのローラ軸をキャリヤに組み付ける作業の自動化が容易な遊星ローラねじ式直動機構を提供する。【解決手段】第1長孔31の幅寸法よりも、第2長孔32の幅寸法の方が広幅とされ、ローラ軸15の第1端部16の外周には、第1回り止め形状部46と第1部分円筒面47とが形成され、第1回り止め形状部46が第1長孔31の長手面45に係合することでローラ軸15が自転しないように回り止めされ、ローラ軸15の第2端部17の外周には第2回り止め形状部49と第2部分円筒面50とが形成され、第2部分円筒面50のみが第2長孔32の長手面48に接触して支持される。【選択図】図2
