In the example shown in the figure, the fixture 57 fixes the pair of reclining members 56 to each other on the back side of the back support 51 . Thereby, the back support body 51 is provided between the pair of reclining members 56, and the swing toward the back side is restricted. The illustrated fixture 57 releasably holds the pair of reclining members 56 . More specifically, the fixture 57 is formed with a through hole through which each of the reclining members 56 is movably passed. Furthermore, the fixture 57 is detachable at any position along the longitudinal direction of each reclining member 56 .

FIG. 7 is a top view showing the back support body 51 and the reclining mechanism 55 taken out from the stroller body 11 and the sheet support unit 50 . FIG. 7 shows the back side of the back support body 51 . As shown in FIG. 7 , a cover member 35 is provided on the back side of the base cloth member 34 . The cover member 35 extends elongatedly in the transverse direction. The cover member 35 has end openings 35a formed at both ends between the cover member 35 and the base fabric member 34 . The corresponding reclining member 56 is inserted from each end opening 35a. A central opening 35b is formed at the center of the cover member 35 in the transverse direction. A pair of reclining members 56 inserted into the path between the cover member 35 and the base fabric member 34 from the end opening 35a extend from the central opening 35b. The fixture 57 is fixed to a pair of reclining members 56 extending from the central opening 35b. The fixture 57 has a size that cannot pass through the central opening 35b. By providing the cover member 35 to the base fabric member 34, a path for the reclining member 56 extending laterally can be formed. Thereby, the reclining member 56 can be used to stabilize and maintain the back support 51 in the swing position. As shown in FIG. 7 , each reclining member 56 may also be covered by a cylindrical cover 58 .

In the stroller 10 having the sheet support unit 50 and the reclining mechanism 55 described above, the relative inclination angle of the back support 51 to the seat support 52 can be easily changed by operating the fixture 57 . In the state shown in FIGS. 1 , 3A , 5 and 6 , the reclining member 56 is pulled into the cover member 35 through the central opening 35 b, and the back support 51 is tilted toward the back side. In the state shown in FIG. 3B , when the reclining member 56 is pulled out from the cover member 35 through the central opening 35 b, the back support 51 will stand up.

Next, the storage basket 80 will be described. As shown in FIGS. 1 to 3B , the storage basket 80 is provided below the sheet support unit 50 . FIG. 8 is a perspective view of the storage basket 80 seen from the rear.

As shown in FIG. 8 , the storage basket 80 is formed by sewing soft fabric. By forming the storage basket 80 from a soft material, the stroller body 11 can be folded while the storage basket 80 is installed on the stroller body 11 . In the example shown in the figure, the storage basket 80 is made of fabric with sufficient strength to support the luggage stored in the storage basket 80 . The so-called high-strength fabric refers to fabrics with high tear strength, rupture strength, and abrasion strength. Of course, the storage basket 80 may also include materials other than fabric. In addition, the storage basket 80 may be formed of materials other than fabric.

The basket 80 has a bottom wall portion 81 forming a bottom surface of the basket 80 . The bottom wall 81 is attached to the body frame 12 below the seat support 52 of the sheet support unit 50 . In the example shown in the figure, the bottom wall portion 81 has a quadrangular shape as a whole, and has a pair of side edge portions 81a extending in the front-rear direction as a whole, and a front edge portion 81b and a rear edge portion 81c extending in the width direction as a whole. The front edge portion 81b connects the front end portions of the pair of side edge portions 81a, and the rear edge portion 81c connects the rear end portions of the pair of side edge portions 81a.

Moreover, in the illustrated example, the storage basket 80 has a pair of side wall parts 85, a front wall part 90, and a rear wall part 95. The entire pair of side wall portions 85 extends in the front-rear direction. The pair of side wall portions 85 are separated from each other in the width direction. The lower edge portion of the side wall portion 85 is connected to the corresponding side edge portion 81 a of the bottom wall portion 81 . The entire front wall portion 90 and the rear wall portion 95 extend in the width direction. The lower edge portions of the front wall portion 90 and the rear wall portion 95 are respectively connected to the front edge portion 81 b and the rear edge portion 81 c of the bottom wall portion 81 . The front edge portion and the rear edge portion of each side wall portion 85 are connected to the front wall portion 90 and the rear wall portion 95 respectively. The side wall portion 85 , the front wall portion 90 and the rear wall portion 95 extend upward from the bottom wall portion 81 . A circumferential wall is formed by the side wall part 85, the front wall part 90, and the rear wall part 95. By having such a circumferential wall, the risk of luggage stored in the storage basket 80 falling from the storage basket 80 can be reduced.

However, strollers often tilt backward when crossing a large step. Therefore, luggage that has been stored in the storage basket will often fall toward the rear. Therefore, it is desirable to make the rear wall of the storage basket higher. In other words, it is desirable to increase the vertical dimension of the rear wall portion. In the illustrated example, the height of the rear wall portion 95 is higher than the height of the front wall portion 90 . Furthermore, as can be understood from FIGS. 3A and 3B , at least a part of the upper edge portion 95 a of the rear wall portion 95 is located above the rear end portion of the seat support 52 . In other words, at least part of the upper edge portion 95a of the rear wall portion 95 is located above the shaft member 30 that rotatably connects the third link L3 and the second link L2 to the handle 40. Thereby, the risk of luggage stored in the storage basket 80 falling rearward from between the bottom wall 81 and the seat support 52 of the storage basket 80 is effectively reduced.

The bottom wall part 81 , the side wall part 85 and the front wall part 90 of the storage basket 80 are installed on the body frame 12 . In the example shown in FIG. 9 , the front edge portion 81 b of the bottom wall portion 81 (that is, the lower edge portion of the front wall portion 90 ) is connected to the front leg 14 through the connector 82 . More specifically, mounting ropes as connectors 82 are attached to both ends of the front edge portion 81 b of the bottom wall portion 81 . The mounting rope 82 is inserted into the through hole 18c formed in the front wheel holding member 18a, and is connected to the front wheel holding member 18a. Moreover, in the example shown in FIG. 10 , the rear edge portion 81 c of the bottom wall portion 81 (that is, the lower edge portion of the rear wall portion 95 ) is connected to the rear leg 16 through the connector 83 . In the example shown in the figure, mounting ropes as connectors 83 are attached to both ends of the rear edge portion 81 c of the bottom wall portion 81 . The mounting rope 83 is inserted into the through hole 19c formed in the rear wheel holding member 19a, and is connected to the rear wheel holding member 19a. The free ends of the installation ropes 82 and 83 are enlarged in size, thereby preventing the free ends of the installation ropes 82 and 83 from being pulled out of the through holes 18c and 19c. Moreover, in the example shown in the figure, the rear edge portion 81c of the bottom wall portion 81 (that is, the lower edge portion of the rear wall portion 95) is further connected to the rear connector 17 through the connector 84. In the example shown in the figure, the mounting cloth as the connector 84 is attached to the center part of the rear edge part 81c of the bottom wall part 81. The installation cloth 84 is connected to the rear connecting member 17 by being wound around the rear connecting member 17 . The mounting cloth 84 is provided with Velcro as a fastener 84a. The mounting cloth 84 uses Velcro felt 84 a to maintain the state of being wound around the rear connecting member 17 .

Moreover, in the example shown in FIG. 10 , the upper edge portion of the side wall portion 85 is connected to the rear leg 16 through the connector 86 . Specifically, an attachment rope as a connector 86 is attached to the center of the upper edge of the side wall portion 85 . The mounting rope 86 is connected to the rear leg 16 by being wound around the connecting portion of the rear leg 16 and the fourth link L4. An annular member serving as a fastener 86a is attached to the free end of the mounting rope 86. The attachment rope 86 maintains the state wound around the connection part of the rear leg 16 and the 4th link L4 using the ring-shaped member 86a.

In the example shown in FIG. 9 , the upper edge portion of the front wall portion 90 is connected to the front leg 14 through the connector 91 .

However, when the height of the rear wall portion 95 is made high, when the sheet support unit 50 is reclined, the back support body 51 and the rear wall portion 95 may interfere with each other, and the back support body 51 may not be tilted to the desired position. The location of the problem. For example, when both ends of the upper edge 95a of the rear wall 95 are connected to the body frame 12 on both sides of the sheet support unit 50, the sheet support unit 50 will swing relative to the body frame 12 when the sheet support unit 50 is reclined. There is a risk of interference between the back support body 51 and the rear wall portion 95 that does not move relative to the main body frame 12 . Taking such a point into consideration, the rear wall portion 95 is attached to the back support body 51 . Thereby, the upper edge part 95a of the rear wall part 95 moves together with the back support body 51. Therefore, when the sheet support unit 50 is reclined, the rear wall portion 95 and the back support 51 are prevented from interfering with each other. In addition, the gap between the upper edge portion 95a of the rear wall portion 95 and the back support body 51 can be maintained at a constant size regardless of the tilt angle of the back support body 51. Furthermore, if the gap between the upper edge portion 95a of the rear wall portion 95 and the back support 51 is too large, the luggage stored in the storage basket 80 may pass through the gap and fall. In addition, if the gap between the upper edge portion 95a of the rear wall portion 95 and the back support 51 is too small, it will be difficult to take out and put in luggage from the storage basket 80 through the gap. Therefore, the size of the gap between the upper edge portion 95a of the rear wall portion 95 and the back support body 51 is maintained constant regardless of the tilt angle of the back support body 51, thereby allowing luggage stored in the storage basket 80 to pass through the above-mentioned The risk of falling due to the gap is reduced, and regardless of the tilt angle of the back support body 51, luggage can be easily taken out and put in from the storage basket 80 through the gap.

In the example shown in FIGS. 8 and 11 , mounting ropes as connectors 96 are attached to both ends of the upper edge portion 95 a of the rear wall portion 95 . Specifically, the mounting cord 96 is connected to the back support body 51 through an endless cord 34c wound around the base fabric member 34 and mounted on the back region 34a. An annular member serving as a fastener 96a is provided at the free end of the mounting rope 96 . The attachment cord 96 is maintained in a state wound around the endless cord 34c using the annular member 96a. Furthermore, FIG. 11 is a plan view showing the upper surface side of the back support body 51 . The upper surface side of the back support body 51 is the opposite side to the back surface side of the back support body 51 shown in FIG. 7 .

In the illustrated example, the upper edge portion 95a of the rear wall portion 95 is detachably connected to the back support 51. Specifically, the mounting rope 96 is detachably connected to the loop rope 34c. Thereby, by removing the rear wall portion 95 from the back support body 51 , the passage for luggage in the rear of the storage basket 80 toward or from the storage basket 80 can be widened. Therefore, larger luggage can be taken out and put into the storage basket 80 through the widened passage.

Furthermore, in the example shown in FIG. 11 , the upper edge portion 95 a of the rear wall portion 95 is connected to the upper surface of the back support body 51 . Specifically, the loop-shaped rope 34c connected to the mounting rope 96 is mounted on the upper surface of the base fabric member 34. Therefore, the mounting rope 96 is connected to the upper surface of the back support body 51 through the width direction outer side of the back support body 51 . In the illustrated example, the attachment cord 96 is connected to the upper surface of the base fabric member 34 through the width direction outer sides of the pair of side frame portions 31 a of the back frame member 31 . Thereby, the upper edge part 95a of the rear wall part 95 can be maintained in the state expanded to the same extent as the dimension of the back support body 51 in the width direction. As a result, the risk of luggage stored in the storage basket 80 falling rearward from between the rear legs 16 is effectively reduced.

Furthermore, in the example shown in FIG. 11 , the upper edge portion 95 a of the rear wall portion 95 is located below the path of the reclining member 56 on the back side of the back support 51 . This reduces the risk that the operation of the reclining member 56 (especially the fixture 57 ) will be hindered by the rear wall portion 95 when the sheet support unit 50 is reclined.
