61, so that the front wheel part 4 can be rotated rearward and folded into the wheel storage part 11, 12 of the body part 2.

FIG. 12 is a bottom view of the baby carriage l. Two insertion grooves 121 and 122 are formed in parallel on the bottom surface of the body portion 2. When the front wheel portion 4 is folded, the connecting rod 74 is accommodated in the insertion groove 121 and is locked by locking protrusions 123 and 124 provided on the left and right sides of the insertion groove 121. The rear wheel part 5 has a leg part 80,
After the fitting 8990 of 81 is released from the stop 9394, it can be folded into the wheel storage 11.12.

When the rear wheel portion 4 is folded, the connecting rod 84 or the insertion groove 122
The locking protrusions 1 are provided on the left and right sides of the insertion groove 122.
25, 126.

FIG. 13 is a diagram illustrating the baby carriage of the present invention in a completely folded state. A paddle part 32 connected to the sub-rod 33 is located at the center of the body part 2 and is used as a convenient grip part for carrying the baby carriage 1.

As shown in FIG. 14, the baby carriage 1 of the present invention has four fitting holes 13013L132, 133 formed in the floor part 10.
(see FIG. 12), a pair of swing legs 135, 1
When 36 is inserted and assembled, it can be used as a rocking chair for infants.

As described in detail above, the foldable baby carriage of the present invention has a simpler structure than the conventional baby carriage and is more stable after assembly, so it has various convenient effects in use.

It goes without saying that the present invention is not limited to the above embodiments, and can be modified in various ways within the scope of the claims.
