It is sandwiched between the walls 9c from above and below.

  Resin support members 11 are attached to both ends of each shade bracket 9 in the longitudinal direction of the vehicle body.

  Each support member 11 includes a substantially oval plate-like arm member 13 as a slider portion. Round portions 13a are formed at both longitudinal ends of one surface of the arm member 13 (outside in the vehicle width direction in the attached state). Round portions 13b are formed on both sides in the width direction of the round portions 13a. A first support shaft 15 protrudes integrally at one end in the longitudinal direction of the other surface (in the vehicle width direction in the attached state) of the arm member 13. At the tip of the first support shaft 15, a pair of branch portions 15a are formed with a gap therebetween so that the pair of branch portions 15a can bend, and each branch portion 15a has a locking portion 15b as a width direction restricting portion. Is formed to project outward in the radial direction. On the other hand, a second support shaft 17 is provided integrally with the other end in the longitudinal direction of the other surface (in the vehicle width direction in the attached state) of the arm member 13. The shaft diameter of the second support shaft 17 is set to be shorter than the length in the vertical direction of the restriction hole 9 h of the shade bracket 9. Further, a bulging portion 19 is integrally formed on the base end side of the second support shaft 17.

  The first support shaft 15 is inserted into the inner through hole 9f and the outer through hole 9g of the shade bracket 9 so as to be rotatable from the outer side in the vehicle width direction. Further, the second support shaft 17 is inserted through the restriction hole 9 h of the shade bracket 9. In this state, the arm member 13 projects to the outside in the vehicle width direction of the shade 3 via the first support shaft 15 and the second support shaft 17. Since the length in the vertical direction of the restriction hole 9h is larger than the shaft diameter of the second support shaft 17, the arm member 13 can tilt up and down. In order to attach the support member 11 to the shade bracket 9, first, the tip of the first support shaft 15 (the branch portion 15a) is first pressed against the inner periphery of the outer through hole 9g, thereby bringing both the branch portions 15a radially inward. The outer through hole 9g is passed while being bent. Then, both branch parts 15a are released from the pressing force from the inner peripheral edge of the outer through hole 9g and return to the original shape, and the diameter of the tip of the first support shaft 15 is the outer through hole 9g (first support shaft 15). ) Larger than the diameter. Next, the tip (branch portion 15a) of the first support shaft 15 is further pressed against the inner peripheral edge of the inner through hole 9f, thereby allowing the inner through hole 9f to pass through while bending both the branch portions 15a radially inward. Then, both branch parts 15a are released from the pressing force from the inner peripheral edge of the inner through hole 9f and return to the original shape, and the diameter of the tip of the first support shaft 15 is the inner through hole 9f (first support shaft 15). It becomes larger than the diameter. In this way, the support member 11 can be attached to the front shade 3 simply by pressing the tip of the first support shaft 15 against the outer through hole 9g and the inner through hole 9f, and the first support shaft 15 can be attached to the through holes 9f and 9g. Since it is not necessary to attach a separate clip serving as the locking portion 15b to the first support shaft 15 after being inserted into the first support shaft 15, assembly man-hours and manufacturing costs can be reduced.

  Further, a torsion coil spring 21 is externally mounted on the first support shaft 15 and is contracted over the entire vehicle width direction between the arm member 13 and the outer wall 9 b of the shade bracket 9. Specifically, one end of the torsion coil spring 21 is locked to the shade bracket 9 and the other end is locked to the arm member 13. Thus, the torsion coil spring 21 always keeps the arm member 13 at the other end in the longitudinal direction of the vehicle body (an end portion on the rear side of the vehicle body for the support member 11 on the front side of the vehicle body, an end portion on the front side of the vehicle body on the support member 11 on the rear side of the vehicle body ) Is tilted in the vertical direction so that it is positioned above one end in the vehicle front-rear direction (the front end of the support member 11 at the front of the vehicle and the rear end of the support member 11 at the rear of the vehicle). It is fast. Thus, the arm member 13 is supported on the shade 3 (shade bracket 9) by the first support shaft 15, and the other end portion in the vehicle longitudinal direction (the support member 11 on the vehicle body front side, the vehicle body rear end portion, the vehicle body In the support member 11 on the rear side, an end portion on the front side of the vehicle body) can be tilted up and down as indicated by a solid line and a virtual line in FIG.

Is different from the front shade 3 in that it is formed longer than the front shade 3. Therefore, the protruding amount of the arm member 13 of the front shade 3 is smaller than the protruding amount of the arm member 13 of the rear shade 5. In addition, an overhang portion 25 is formed in an overhanging manner so as to connect the first support shaft 15 and the second support shaft 17 of each support member 11 of the rear shade 5 in the protruding direction. The overhang portion 25 and the arm member 13 are connected to each other by a connecting plate portion 26 that bridges the first support shaft 15 and the second support shaft 17. A torsion coil spring 21 is contracted between the overhang portion 25 and the outer wall 9 b of the shade bracket 9, and the other end of the torsion coil spring 21 is engaged with the overhang portion 25 instead of the arm member 13. . Further, on the first support shaft 15 of both support members 11 on the front side of the rear shade 5, a hook 27 as a connecting mechanism having a flange portion 29 at the tip is rotated between the inner wall 9 a and the outer wall 9 b of the shade bracket 9. A torsion coil spring 31 is externally mounted. The torsion coil spring 31 urges the hook 27 so that the protruding direction of the flange 29 is downward.
