The first engagement portion is engaged with a first engaged portion of the one end portion. The second engagement portion is engaged with a second engaged portion of the one end portion in the same position as a position of engagement between the first engagement portion and the first engaged portion in the seat width direction or in a position on the inner side from the position of engagement in the seat width direction, the second engaged portion being positioned closer to one end of a biasing member in the extension direction than the first engaged portion.
