PURPOSE:To obtain a seat revolving apparatus having a simple structure and the superior strength by installing a rotary center shaft onto an attachment bracket bridged and fixed on seat tracks and installing a cylindrical rotary body on a seat side member. CONSTITUTION:An attachment bracket 10 consists of band-shaped plates 12 and 13 which cross in X-figure-form and is fixed onto seat tracks 1 and 2. The lower edge part of a rotary center shaft 11 is inserted and fixed into the cross part of the band-shaped plates 12 and 13. An upper bracket 20 is fixed onto the both side parts of a seat frame 3, and a cylindrical part 23 is formed in the center part of the upper bracket, and the upper edge part of the cylindrical rotary body 21 is inserted and fixed therein. The outer flange 24 of the cylindrical rotary body 21 is attached onto the upper band-shaped plate 12, and a cylindrical body 18 having an outer flange 17 is fixed at the upper edge of the rotary center shaft 11. A proper lock mechanism 30 is installed between the rotary center shaft 11 and the cylindrical rotary body 21. |
