CONSTITUTION:Forward force acts on an occupant and a seat at the time of a head-on collision of a vehicle and a seat cushion 14 is forced to be moved forward but the forward movement of the seat cushion is checked by a front part 16 of a seat cushion arrangement portion 15 of a floor panel 12 since the front part 16 is set to a position upper than a hip point P of the occupant. A hook 21 is inserted to and locked up in a grommet 18 and an engaging state between the hook 21 and the grommet 18 is more ensured since a component of force F2 of a force F acted on the seat cushion in the direction inserting the hook 21 into the grommet 18 acts in the direction pushing the hook 21 into the grommet 18. |
