Abstract: A conveyance seat includes a cushion frame. The cushion frame includes side frames disposed on right and left sides in a seat width direction, and a pan frame (connecting frame) connecting the right and left side frames. The side frames includes respective engagement protrusions (engaging portions) that engage with engagement recesses (engaged portions) provided in the pan frame, to position the pan frame. The engagement protrusions are formed to protrude toward an engagement recess side in a facing direction (up to down direction) in which the side frames and the pan frame face each other. The engagement recesses engage with the respective engagement protrusions by coming into contact with the respective engagement protrusions in an intersecting direction intersecting with the facing direction.
