PROBLEM TO BE SOLVED: To provide a planetary roller screw type linear motion mechanism of which assembly is easy.SOLUTION: A carrier 14 has two discs 21, 23 holding first and second end parts 13a, 13b of a support pin 13. A first pin storing hole 41 formed at the first disc 21 has a guide surface 44 having a shape changing a position in a radial direction of the first end part 13a of the support pin 13 when the first end part 13a of the support pin 13 is displaced in a circumferential direction in the first pin storing hole 41. A second pin storing hole 43 formed at the second disc 23 has a guide surface 50 having a shape in which a position of the second end part 13b of the support pin 13 is displaced in its radial direction when a second end part 13b of the support pin 13 is displaced in a circumferential direction.SELECTED DRAWING: Figure 9

    【課題】組み立て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】キャリヤ14は、支持ピン13の第1および第2の端部13a,13bを保持する2枚のディスク21,23を有する。第1のディスク21に形成された第1のピン収容穴41は、第1のピン収容穴41内で支持ピン13の第1の端部13aを周方向に変位させたときに支持ピン13の第1の端部13aの径方向位置を変化させる形状の案内面44を有する。第2のディスク23に形成された第2のピン収容穴43は、支持ピン13の第2の端部13bを周方向に変位させたときに支持ピン13の第2の端部13bの径方向位置を変化させる形状の案内面50を有する。【選択図】図9
