Further, in the illustrated example, the third link member 23 is arranged outside the corresponding handle extension portion 42 and the rear leg 35 in the width direction. Therefore, the third link member 23 having the shape described above can hide the connecting portion between the handle 40 and the rear leg 35 in a side view of the baby carriage body 20 in the unfolded state. This also improves the design of the baby carriage body 20 .
- the baby carriage main body 20 having the overall configuration as described above can be folded by rotating each component. Specifically, the handle 40 is lifted rearward and upward to some extent, and then the handle 40 is lowered to rotate the third link member 23 with respect to the rear leg 35 in the clockwise direction in FIGS. 2 and 3 . With this operation, the first link member 21 and the second link member 22 are rotated clockwise in FIGS. 2 and 3 with respect to the handle extension portion 42 . As shown in FIGS. 2 and 3, this operation causes the handlebar 40 and the front leg 30 to approach each other and be arranged substantially parallel in side view, and the position of the handlebar 40 is lowered. As described above, the baby carriage body 20 can be folded. The baby carriage main body 20 can be reduced in size in the longitudinal direction and the vertical direction in the folded state shown in FIGS. 2 and 3 . On the other hand, in order to unfold the baby carriage body 20 from the folded state, the folding operation described above may be reversed.
- the seat 60 is a part on which an infant sits. As shown in FIG. 8, the seat 60 has a pair of bases 61 spaced apart in the width direction. The base portion 61 is a portion to be supported by the holding member 50 provided on the baby carriage body 20 .

- the back portion 70 may further have a cloth-like member or plate-like member supported by the rear frame member 71 .
- the seat 60 has a pair of side support portions 72 extending upward from each base portion 61, as shown in FIG.
- the side support portion 72 supports the side frame member 73 so as to be rotatable around a rotation axis X8 parallel to the width direction.
- a pair of connecting frame members 74 are provided between the side frame member 73 and the rear frame member 71 .
- a pair of connecting frame members 74 are arranged with a gap in the width direction.
- the connecting frame member 74 is rotatable with respect to the rear frame member 71 and the side frame members 73 .
- the connecting frame member 74 functions as a link member, and causes one of the rear frame member 71 and the side frame member 73 to swing as the other swings.
- connection frame member 74 forms a wall portion positioned behind the head of the infant with the back portion 70 lying down, between the rear portion of the rear frame member 71 and the rear portion of the side frame member 73 . , forming a wall that lies behind the infant's head with the back 70 upright.
- the seat 60 has a pair of guard support members 75 extending from each base 61, and a detachable guard member 76 between the pair of guard support members 75. there is
- the seat 60 also has a pair of canopy support members 77 fixed to the side support portions 72, respectively.

- the pair of holding members 50 are spaced apart in the width direction.
- the baby carriage body 20 holds the seat 60 at a position between the pair of first link members 21 in the width direction by the pair of holding members 50 .
- the holding member 50 has a support portion 51 that supports the supported portion 63 provided on the seat 60 and a connection portion 55 that connects the support portion 51 to the handle 40 .
- the support portion 51 has a receiving hole 53 that opens upward or an insertion portion that protrudes upward.
- the supported portion 63 can be configured as a downwardly protruding insertion portion that can be inserted into the receiving hole 53 of the supporting portion 51 or as a downwardly opening receiving hole into which the inserting portion of the supporting portion 51 can be inserted.
- the support 51 has a receiving hole 53 formed in an upwardly facing support surface 52 .
- the support surface 52 extends in the front-rear direction.
- a receiving hole 53 that opens upward is formed in the central portion of the support surface 52 in the front-rear direction.
- the supported portion 63 of the seat 60 is provided on each base portion 61 .
- the base 61 has a supported surface 62 facing downward.
- the supported surface 62 extends in the front-rear direction corresponding to the supporting surface 52 .
- An insertion portion forming a supported portion 63 protrudes downward from the central portion of the supported surface 62 in the front-rear direction.
- the seat 60 is held on the baby carriage body 20 via the holding member 50 by lowering the seat 60 onto the baby carriage body 20 from above in the vertical direction. becomes possible. More specifically, by lowering the seat 60 , the supported portions 63 protruding downward from each of the pair of base portions 61 are inserted into the receiving holes 53 of the corresponding support portions 51 of the holding member 50 . The seat 60 is held on the baby carriage body 20 by contacting the supported surface 62 of the base 61 with the supporting surface 52 of the holding member 50 . Since the supporting portion 51 is engaged with the supported portion 63 while the seat 60 is held by the stroller body 20 , the horizontal movement of the seat 60 relative to the stroller body 20 is restricted.
- the holding member 50 can hold the seat 60 while changing its front-rear direction. As a result, by simply changing the orientation of the seat 60, the infant shown in FIG. It is possible to switch between a face-to-face state in which the operator (guardian) faces the operator (guardian).
- the pair of holding members 50 and the pair of bases 61 are spaced apart in the width direction. Therefore, in a state in which the seat 60 is held by the stroller body 20, there is a deviation due to relative rotation between the seat 60 and the stroller body 20 centering on the axis along the longitudinal direction, and the seat centering on the axis along the vertical direction. 60 and baby carriage main body 20 can be effectively restricted from shifting due to relative rotation.
- the supporting surface 52 extends forward and backward of the receiving hole 53
- the supported surface 62 extends forward and backward of the supported portion 63 .
- the seat 60 in a state in which the seat 60 is held by the stroller body 20, it is possible to effectively prevent deviation due to relative rotation between the seat 60 and the stroller body 20 about the axis along the width direction. As described above, the seat 60 can be stably held by the baby carriage body 20 .
- the seat 60 is held between the pair of first link members 21, between the pair of front legs 30, between the pair of rear legs 35, and between the pair of handle extensions 42.
- Such arrangement of the seat 60 makes it possible to avoid interference with the components of the baby carriage body 20 . That is, the holding member 50 can hold the seat 60 so that the seat 60 is separated from the baby carriage body 20 . Furthermore, such an arrangement of the seat 60 can also avoid interference between the stroller main body 20 and the seat 60 during the folding operation. Therefore, as shown in FIGS. 2 and 3, the baby carriage body 20 can be folded while the seat 60 is held. In the illustrated baby carriage 10, the baby carriage 10 can be folded while the seat 60 is held by the baby carriage main body 20 in both the facing state and the rear side state.
