Abstract
A lock mechanism which is capable of selecting a locked state or an unlocked state with respect to a seat fixing member is disposed on a rear leg portion of a seat. A hook portion is formed at each of a front portion and a rear portion of an opening portion of a notch formed in a front leg portion of the seat. A projection of a base hook which is swingably connected to the front leg portion is engageable with an engaging projection of a cam that is swingably connected to the front leg portion. The cam is engaged with a spring for urging the cam in a direction in which the engaging projection engages with the projection. Due to a hook portion of the front leg portion passing beneath a pin which is disposed in a rail and which has reached a bottom of a groove in the base hook, the seat and the pin are prevented from becoming disengaged from each other. Hence, a seat structure for a vehicle is provided which reduces the weight of the seat and improves operating efficiency with respect to changing the position of the seat relative to a vehicle body.
