<p><P>PROBLEM TO BE SOLVED: To provide a through anchor of a seat belt with sufficient durability of a cylindrical body, capable of being constituted at low cost. <P>SOLUTION: A shaft 5 is non-rotatably supported on an anchor base 3, and the cylindrical body 6 is rotatably externally fitted to the shaft 5. A recession part 12 engageable with a projection corner part 5t of the shaft 5 is provided on an inner peripheral surface of the cylindrical body 6. The cylindrical body 6 is vertically movably supported on the shaft 5 through a bearing 9. A leaf spring 11 for vertically urging the bearing is provided between the bearing 9 and the shaft 5 such that the recession part 12 of the cylindrical body 6 and the projection corner part 5t of the shaft are left from each other. When pressing force of a predetermined value or more is applied from a seat belt to the cylindrical body 6, the cylindrical body 6 is downwardly moved in resistant to the urging force of the leaf spring 11. Thereby, the projection corner part 5t of the shaft 5 is engaged with the pressing force 12 of the cylindrical body 6 and rotation of the cylindrical body 6 is inhibited. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
