Abstract
The submarine phenomenon can be prevented and the accuracy of a passenger'"'"'s weight measurement is improved. A vehicle seat includes a pair of fixed lower rails fixed on the floor of a passenger compartment, a pair of movable upper rails that are engaged with the fixed lower rails so as to be slidable in a front-and-rear direction with respect to each of the fixed lower rails, a sub frame which is disposed at an upper side of the movable upper rails, load sensors and that lie between the sub frame and the movable upper rails, brackets and which are disposed so as to erect them on each of the movable upper rails, and a submarine pipe 11 which is crossed between the brackets. The submarine pipe is disposed to be slidable in a left-and-right direction with respect to the right bracket.
