The rear edge faces the lower end of the rear window glass (not shown).

  The parcel shelf 15 includes a flat metal panel 16 and a synthetic resin lining 17 having an L-shaped cross section. The lining 17 has a main body portion 17a covering the upper surface of the panel 16, and a front end of the main body portion 17a facing downward. And a front wall portion 17b bent in a straight line. A cross member 18 having a U-shaped cross section that connects the left and right rear pillars in the vehicle width direction includes a front wall 18a and a rear wall 18b that extend in the vertical direction, and a bottom wall 18c that connects the lower ends of the front wall 18a and the rear wall 18b. The upper ends of the front wall 18a and the rear wall 18b are connected to the lower surface of the front end portion of the panel 16 of the parcel shelf 15 to form a closed cross section.

  The lock mechanism 19 that locks the right side portion 13R of the seat back 13 in the upright position includes a detachable striker 20 and a latch 21. A support member 23 extending in the vehicle width direction is fixed to a seat frame 22 embedded in the rear surface of the seat back 13, and a pair of left and right guide pipes 24, 24 extending in the vertical direction are fixed to the support member 23. A bifurcated lower portion of an inverted U-shaped guide rod 25 with the upper portion embedded in the headrest 14 is slidably fitted to the pair of guide pipes 24, 24, so that the headrest 14 is adapted to the occupant's physique. The vertical height can be adjusted. The striker 20 whose front end is fixed to the support member 23 protrudes rearward from the upper end portion of the right side portion 13R of the seat back 13, and a loop-shaped engagement portion 20a formed at the rear end is formed on the front wall portion 17b of the lining 17. It can be fitted into the vertically long opening 17c.
