To provide a vehicular seat device, which is configured so that rotation rattling does not occur in a rotating member and manufacturing costs for the device can be reduced.SOLUTION: In the vehicular seat device, in a base member a tap hole or a mounting hole which serves as a support hole is formed at a position corresponding to a center of a rotary shaft thereof, and in a rotating member a mounting hole is formed at a position corresponding to a center of a rotary shaft thereof. A thrust bearing is arranged on the rotating member so that the bearing is concentric to a round hole of the rotating member. A thrust fastening bolt is inserted through an inner diameter part of the thrust bearing from above. After a tip screw part of the thrust fastening bolt is screwed to the tap hole of the base member or after the tip screw part of the thrust fastening bolt is inserted through the mounting hole of the base member, a nut is screwed to the tip screw part of the thrust fastening bolt protruding downward from the base member, so that the rotating member is tucked between the thrust bearing and the base member.SELECTED DRAWING: Figure 2
【課題】本発明の車両用シート装置は、回転部材に回転ガタが発生しないこと、その製造コストの低減を図ることにある。【解決手段】ベース部材は、その回転軸中心相当位置に支持孔となるタップ孔または取付け孔が設けられ、回転部材は、その回転軸中心相当位置に取付け孔が設けられ、回転部材の丸孔と同芯となるように回転部材上にスラストベアリングが配備され、このスラストベアリングの内径部に上方よりスラスト締付けボルトが挿通され、このスラスト締付けボルトの先端ネジ部が前記ベース部材のタップ孔に螺合された後、または、前記ベース部材の取付け孔にスラスト締付けボルトの先端ネジ部が挿通された後、ベース部材より下方へ突出するスラスト締付けボルトの先端ネジ部にナットが螺合され、前記スラストベアリングと前記ベース部材の間に前記回転部材が挟み込まれてなる車両用シート装置。【選択図】図2
