<p>PROBLEM TO BE SOLVED: To improve holding strength of a member to a tensile load in a back- and-forth and upward direction of a seat, without increasing resistance at rotating in a seat rotating device. SOLUTION: This seat rotating device A comprises a lower frame 11b a vehicular floor side member B, and having a first hook portion extending to a floor side; an upper frame 12 engaged with an upper surface of the first hook portion through a first supporting member 14, and fixed to a vehicular seat side member C; and an a sub frame 13 engaged with a lower surface of the first hook portion through a second supporting member 15, fixed to the vehicular seat side member C together with the upper frame 12 while being coupled to the upper frame 12, and having a second hook portion 13b extending to a seat side. The first supporting member 14 and the second supporting member 15 are structured by balls, an engaging portion 13c of the sub frame 13 with which the second supporting member 15 is engaged is structured as a tilting surface formed by bending a tip end of the second hook portion 13b extending to the seat side to the floor side.</p> |
