Title (EN) POWER STEERING DEVICE
(FR) DISPOSITIF DE DIRECTION ASSISTÉE
(JA) パワーステアリング装置
Abstract:
(EN) Provided is a power steering device wherein the accuracy of the relative positions of a first circulation member and a second circulation member is improved. A tube 23 is provided with: a first first-tube-side contact section 40 and a second second-tube-side contact section 51, which restrict the circumferential relative positions of a first tube 31 and a second tube 32 relative to a nut 8; and a second first-tube-side contact section 41 and a first second-tube-side contact section 51.
(FR) La présente invention concerne un dispositif de direction assistée dans lequel la précision des positions relatives d’un premier élément de circulation et d’un deuxième élément de circulation est améliorée. Un tube 23 est pourvu de : une première section de contact côté premier tube 40 et une deuxième section de contact côté deuxième tube 51, qui limitent les positions relatives circonférentielles d’un premier tube 31 et d’un deuxième tube 32 par rapport à un écrou 8 ; et une deuxième section de contact côté premier tube 41 et une première section de contact côté deuxième tube 51.
(JA) 第1循環部材と第2循環部材との相対位置精度を向上できるパワーステアリング装置を提供する。 チューブ23は、ナット8に対する第1チューブ31および第2チューブ32の周方向相対位置を規制する第1の第1チューブ側当接部40および第2の第2チューブ側当接部51と、第2の第1チューブ側当接部41および第1の第2チューブ側当接部51とを備える。
