Description of the Invention: [Technical Field of the Invention] The present invention relates to the dimensions of the direction of the trolley and the stroller in the direction of the width direction and the direction of the width of the stroller. Folding infants of size and size = first and the baggage handling vehicle have a wide range of meanings: 45.13549, the Japanese mosquitoes are fair, and the size of the height direction and the width direction are extended in the up and down direction. It is configured such that the leg is bent toward the rigid side with respect to the push rod extending in the up and down direction to reduce the height of the folded state. Moreover, the size of the stroller in the width direction will be reduced. In order to make the above-mentioned width: open, the rear leg and the pusher are connected by a back cross member composed of two lever members that are crossed into an x-shape. ❹ B & Ben: A stroller disclosed in Japanese Patent Publication No. 45-13549 and Japanese Patent Publication No. Hei 7-12824, wherein the pair of pushers are configured to be bent forward to reduce the height of the folded state. For example, in Japanese special watches 2001_525291 5.52237 -; other strollers that reveal other publications are made by words. Patent Document 2 料本实公昭45-13549号JP-A-2001-525291 (Patent Document 4): JP-A-2005-522372 (Summary of the Invention) In the stroller, the upper portion of the back side member is coupled to the back side of the pair of push rods, so that it is difficult to provide the backrest portion between the rods with the back tilt. In the stroller having the (four) screw, which is disclosed in the Japanese Patent Publication No. 2001-525372, and the Japanese Patent Publication No. 2005-522372, since there is no obstacle member on the back surface of the push rod, it is possible to The backrest portion can be provided with a backward tilt. Focusing on this point of view, it can be said that a baby-free car with a sliding pusher is preferred. In the case of a baby car having a sliding pusher, since it is difficult to provide a back cross member that connects the pair of pushers and the pair of rear legs, it takes some effort to reduce the size in the width direction in the folded state. . In the Japanese Patent Publication No. 2005-522372, there is no record in the configuration in which the size in the width direction is reduced in the folded state of the stroller. In the Japanese Patent Publication No. 2001-525291, the idea of shrinking the width in the width direction of the stroller is described, but the specific structure for achieving the object is not described. SUMMARY OF THE INVENTION An object of the present invention is to provide a folding stroller in which a squat type (four) is reduced in size and folded in a baby carriage having a sliding pusher. 321083 5 201033058 Another object of the present invention is to provide an early configuration of ρ between the rear direction and the width direction to make the front (the (four) type trolley of the hand 1 of the problem solved. * To the width of the width = two: = the folding type of the invention The trolley is a narrow front and rear vertical frame member, and the trolley of the stack is provided with: - a positional relationship between the first and the second, and a second longitudinal frame member in the upper and lower sides. And a pair of upper parts of the frame member; the first - X-shaped two rod members, the upper end portion of which can be forked to the first longitudinal frame member, and the one-month movement is also supported by a pair of g /, lower end portions Rotatablely coupled to a pair of first fr frame members. The pair of side frame members are rotatably coupled to the first piece by a flat (four) position and a second end thereof.
