Description

  The present invention relates to a hood lever and a hood structure for a stroller attached to the stroller.

  Conventionally, a stroller hood has been provided with a plurality of hood bones and a hood cloth attached to the hood bone, and at least one hood bone has to be separated from other hood bones or be close to other hood bones. It can be swung freely. At this time, when the hood bones are rocked so as to be separated from each other, the hood is in an open state, and when the hood bones are rocked so as to approach each other, the hood is in a closed state.

  The hood further includes a hood lever that connects the hood bones. Usually, the hood lever has a first hood lever and a second hood lever, and the vicinity of one end of the first hood lever and the vicinity of one end of the second hood lever are rotatably connected by a rivet, and the other end of each. The parts are connected to different hood bones. That is, when the hood is opened, the first hood lever and the second hood lever are extended in a straight line so that the hood bones can be separated from each other. The other end of the lever is separated. On the other hand, when the hood is closed, the first hood lever and the second hood lever are pivoted around the connecting part by the rivet so that the hood bones can approach each other.

The first hood bone 77a on the front side and the second hood bone 77b on the rear side are connected to a boss 78 at the ends. Of these, the first hood bone 77 a is swingable with respect to the boss 78, whereby the first hood bone 77 a can swing with respect to the second hood bone 77 b and the hand barb 11.

  As shown by a dotted line in FIG. 2, the hood cloth 76 is attached to the first hood bone 77a and the second hood bone 77b, and the first hood bone 77a and the second hood bone 77b with the hood 75 open. It will be in a state stretched between. Further, the rear side of the hood cloth 76 is attached to the vicinity of the upper end of the backrest (not shown) of the stroller 10.

  Next, the hood lever 80 will be described in detail with reference to FIGS. The pair of hood levers 80 has a symmetrical structure, and the hood lever 80 shown in FIGS. 13 to 17 is a hood lever 80 disposed on the right side when the stroller 10 is viewed from the front. The side facing inward in the width direction is shown as being the upper side in the figure.

  As shown in FIGS. 13 to 17, the hood lever 80 includes a first hood lever 81 having a guide groove 82 opened toward one end 81a and a fitting hole 83 provided at the end of the guide groove 82; And a second hood lever having a cylindrical fitting boss 93 that engages with the fitting hole 83 of the first hood lever 81.

  The first hood lever 81 and the second hood lever 91 are in the open position by fitting the fitting hole 83 of the first hood lever 81 and the fitting boss 93 of the second hood lever 91 (FIG. 14). It rotates between (a) and FIG. 15 (a)) and a closed position (FIG. 14 (b) and FIG. 15 (b)).

  First, the first hood lever 81 will be described.

  As shown in FIG. 13, the first hood lever 81 has an elongated flat plate shape, and has one side surface 85 disposed on the upper side and the other side surface 86 disposed on the lower side when incorporated in the stroller 10. doing. In addition, one end 81a of the first hood lever 81 provided with the guide groove 82 has a substantially semicircular shape, and a fitting hole 83 is disposed at substantially the center of the semicircle. Therefore, the one side surface 85 has a substantially arcuate portion 85a having a substantially arcuate cross section corresponding to the substantially semicircular end 81a, and a substantially linear portion 85b having a substantially rectilinear cross section adjacent to the upper part of the arc ( For example, FIG. Similarly, the other side surface 86 also has an arcuate portion 86a having a substantially arcuate cross section corresponding to the substantially semicircular end 81a, and a substantially linear portion 86b having a substantially rectilinear cross section adjacent to the upper part of the arc. .

  The guide groove 82 extends in the longitudinal direction of the first hood lever 81, and the width of the guide groove 82 is the widest at the tip end portion 82a and gradually narrows toward the back end portion 82b. The width of the guide groove 82 at the front end 82a is larger than the diameter of the fitting boss 93 of the second hood lever 91, and the width of the guide groove 82 at the inner end 82b of the fitting boss 93 of the second hood lever 91. It is smaller than the diameter (FIG. 16 (a)). Further, the inner diameter of the fitting hole 83 provided adjacent to the rear end portion 82 b of the guide groove 82 is slightly larger than the diameter of the fitting boss 93 of the second hood lever 91.

  Further, when the hood lever 80 is incorporated in the stroller 10, a positioning projection 84 is provided in the vicinity of the fitting hole 83 on the inner side surface 81b facing the width direction inner side of the stroller 10 (FIG. 13). Further, a connecting boss 87 for connecting the first hood lever 81 to the first hood bone 77a is provided at the other end 81c of the first hood lever 81 (FIG. 13). The connecting boss 87 passes through the first hood bone 77a and the hood cloth 76, and then a ring (not shown) is fitted into a substantially spherical spherical connecting portion 87a provided at the tip thereof. In this way, the first hood lever 81 is rotatably connected to the first hood bone 77a.

  Next, the second hood lever 91 will be described.

  As shown in FIG. 13, the second hood lever 91 has an elongated flat plate shape having a slit 92 on one end 91a side. The slit 92 is open toward the side surface, and a cylindrical fitting boss 93 is disposed in the slit 92. That is, one end 81 a of the first hood lever 81 is fitted into the slit 92 of the second hood lever 91.

  As shown in FIG. 15, the bottom portion of the slit 93 is in contact with the side surfaces 85 and 86 of the first hood lever 81 and constitutes a regulating portion 95 that regulates the rotation of the first hood lever 81 relative to the second hood lever 91. ing. Such a restricting portion 95 has a substantially open V shape, and is between the first restricting portion 95a and the second restricting portion 95b having two substantially straight sections, and between the first restricting portion 95a and the second restricting portion 95b. And a third restricting portion 95c having a substantially arcuate cross section that is disposed and engages a substantially semicircular end 81a of the first hood lever 81. In addition, the diameter of the 3rd control part 95c is a little larger than the diameter of the end of the 1st hood lever 81 which is semicircle shape.

  For this reason, as shown in FIG. 15A, when the hood lever 80 is in the open position, the substantially straight portion 85 b of the one side surface 85 of the first hood lever 81 is the first of the second hood lever 91. While being in contact with the restricting portion 95a, the arc-shaped portion 85a of the one side surface 85 of the first hood lever 81 is disposed close to the third restricting portion 95c. On the other hand, as shown in FIG. 15B, when the hood lever 80 is in the closed position, the substantially straight portion 86 b of the other side surface 86 of the first hood lever 81 is the second restriction of the second hood lever 91. While being in contact with the portion 95b, the arc-shaped portion 86a of the other side surface 86 of the first hood lever 81 is disposed close to the third restricting portion 95c.

  In addition, two positioning holes 94 a and 94 b are provided on the inner wall 92 b of the slit 92 disposed on the inner side in the width direction of the stroller 10 with the fitting boss 93 interposed therebetween when the stroller 10 is assembled. As shown in FIG. 14A, when the hood lever 80 is in the open position, the first positioning hole 94a arranged on the one end 91a side from the fitting boss 93 and the positioning projection 84 of the first hood lever 81 are engaged. In addition, the positional relationship between the first hood lever 81 and the second hood lever 91 is fixed. On the other hand, as shown in FIG. 14B, when the hood lever 80 is in the closed position, the other second positioning hole 94b and the positioning projection 84 of the first hood lever 81 are engaged, and the first hood lever 80 is engaged. The positional relationship between 81 and the second hood lever 91 is fixed.

  Furthermore, a connecting boss 97 for connecting the second hood lever 91 to the second hood bone 77b is provided at the other end 91c of the second hood lever 91. The connecting boss 97 passes through the second hood bone 77b and the hood cloth 76, and then a ring (not shown) is fitted into a substantially spherical spherical connecting portion 97a provided at the tip thereof. In this way, the second hood lever 91 is rotatably connected to the second hood bone 77b.

  In addition, the material of the 1st hood lever 81 and the 2nd hood lever 91 which consists of the structure mentioned above is comprised from flexible materials, such as resin, for example.

  Next, the operation of the present embodiment having such a configuration will be described.

  First, a method for folding the stroller 10 from the unfolded state will be described.

  In this case, first, while pushing the lock operating device 100 so that the bracket 13 rotates about the connecting shaft with the rear leg 31 in the clockwise direction in FIG. Pull up in the direction, then push down. At this time, along with the rotation of the bracket 13 with respect to the rear leg 31, the hand barb 11 is arranged substantially parallel to the rear leg 31 while being moved to the lower position.

  Further, the armrest 40 and the frame 17 pivotally attached to the hand barb 11 rotate in the clockwise direction in FIG. 2 with respect to the hand barb 11 and are inclined so that the rear side is arranged downward. As a result, the front leg 21 and the hand pusher 11 are moved so as to approach each other while maintaining a substantially parallel state, and the longitudinal dimension of the stroller 10 is reduced as shown in FIG.

  On the other hand, as shown in FIGS. 2 and 4, the length of the X-shaped link 71 as viewed from the side of the stroller 10 becomes longer as the frame 17 rotates with respect to the hand barb 11. At this time, the links 71 a and 71 b of the X-shaped link 71 rotate with respect to each other so as to extend in the front-rear direction of the stroller 10. With the rotation of the X-shaped link 71 in the closing direction, the hand barb 11 connected to the X-shaped link 71 via the extension bar 15 is provided on the horizontal barb portion 11b so as to narrow the interval at the lower end. It swings around a hinge (not shown).

  In addition, the front leg 21 and the rear leg 31 connected to the hand barb 11 via the armrest 40 are also swung around a hinge (not shown) provided on the horizontal barb 11 b of the hand bar 11 so as to narrow the interval. As a result, the width dimension of the stroller 10 is reduced as shown in FIG.

  At this time, the front leg stay 62 is biased so that the central portion 62a protrudes upward and forward by the rotation of the X-shaped link 71 in the closing direction. Further, when the connecting rod 66 is pushed down as the frame 17 rotates, the footrest portion 65a of the footrest 65 is urged to protrude upward. Further, the connecting rod 69 is pulled up with the rotation of the bracket 13, whereby the rear leg stay 68 is urged so that the central portion 68a protrudes upward and forward. By operating the front leg stay 62, the rear leg stay 68, and the footrest 65 connecting the pair of front legs 21 and the pair of rear legs 31 in this manner, the front legs 21 and the rear legs 31 can approach smoothly.

  In addition, the front legs 21 and the rear legs 31 are disposed so as to be inclined so that the distance between the legs widens downward. Therefore, even if the distance between the front legs 21 and the rear legs 31 is reduced by swinging around the hinge (not shown) of the hand barb 11 as shown in FIG. 5, as shown in FIG. Can be prevented, or the front leg 21 or the rear leg 31 can be prevented from coming into contact with a member or the like disposed between the legs.

  Further, when the armrest 40 swings and narrows the space around the hinge (not shown) provided on the horizontal hook portion 11b of the hand barb 11, it is necessary to bend the guard arm main body 57 in a compact and small manner. According to the present embodiment, the armrest joint 46 that locks the guard arm 56 can swing from the deployed position to the folded position with respect to the armrest body 41. Therefore, when the stroller 10 is folded, the armrest joint 46 is pressed to the folding position, that is, to the armrest body 41 in the width direction outside by the bending resistance of the guard arm body 57. Thereby, the bending of the guard arm main body 57 bent by folding the stroller 10 can be loosened, and the folding resistance of the stroller 10 can be reduced.

  Further, since it is not necessary to bend the guard arm main body 57 small and tightly, the number of joints of the aggregate 57b of the guard arm main body 57 can be reduced, and a flexible material 57a can be used having high rigidity. Thereby, since the rigidity of the guard arm 56 can be improved, an infant can be protected more safely.

  Further, when the stroller 10 is folded, the inclination angles of the front legs 21 and the rear legs 31 change, but the wheel shafts 23b and 33b of the wheels 23 and 33 are always arranged parallel to the ground contact surface. Therefore, it is possible to always smoothly run the wheels 23 and 33 regardless of whether the stroller 10 is folded or unfolded. In the present embodiment, each wheel 23, 33 has a double-wheel structure that requires a manufacturing system. By configuring each caster holder 26, 36 as described above, the wheel shaft 23b, Since 33b is arranged in parallel to the ground plane, a manufacturing error can be corrected, and as a result, quality can be improved.

  On the other hand, when the folded stroller 10 is to be unfolded, the hand barb 11 is pulled up and the bracket 13 is rotated counterclockwise in FIG. 4 with respect to the rear leg 31 about the connecting shaft with the rear leg 31. . Thereby, the stroller 10 is unfolded in the reverse procedure to the case of folding, and the state shown in FIG. 2 is obtained. In this case, the lower end of the tube portion 11 a of the hand barb 11 comes into contact with the rear leg, and the engagement pin 15 c of the hand barb 11 engages with the engagement groove 13 c of the bracket 13. As a result, the positional relationship between the push bar 11, the rear leg 31 and the bracket 13 is fixed.

  Thus, by raising and lowering the hand pusher 11, the stroller 10 can be easily folded and can be easily deployed.

  At this time, the armrest joint 46 is returned to the deployed position by the pressing of the spring contact rib 49 b by the compression coil spring 45 and the restoring force of the guard arm main body 57.

  Next, the case where the stroller 10 is used will be described. When an infant is put on the stroller 10, the guard arm 56 is once removed from the armrest 40. In this case, first, the release button 59c of the guard arm joint 58 is pushed. Thereby, since the engaging protrusion 51a of the armrest joint portion 46 enters the engaging portion 51, the guard arm 56 can be easily pulled out from the armrest 40.

  After the infant is put on the stroller, the guard arm 56 is attached to the armrest 40 again. In this case, the armrest joint 46 is biased by the compression coil spring 45 and is always disposed at the deployed position, that is, substantially in front of the armrest body 41. For this reason, it is not necessary for the guardian to adjust the position of the armrest joint 46, or the guard arm 56 can be easily attached to the armrest 40 without deforming the guard arm main body 57.

  Further, since the opening 59 of the guard arm joint portion 58 has a guide portion 59a whose opening diameter increases outward, the engagement protrusion 51a of the engagement portion 51 is formed along the inclined surface of the guide portion 59a. Can enter the engaging portion 51, and the engaging protrusion 51 a does not prevent the engaging portion 51 from being inserted into the opening 59. On the other hand, the engaging protrusion 51a protrudes to the side by a biasing force of a spring (not shown) and engages with the step 59b in a portion where the diameter in the vicinity of the bottom surface of the opening 59 is large. As a result, the guard arm joint 58 is locked to the armrest joint 46. As described above, according to the present embodiment, the guard arm 56 can be easily attached to the armrest 40 simply by pushing the engaging portion 51 of the armrest joint portion 46 into the opening 59 of the guard arm joint portion 58.

  Further, when the stroller 10 is deployed, the front legs 21 and the rear legs 31 are both inclined downward so that the distance between the legs spreads in the width direction. Force acts only in the direction. Thereby, the load applied to the front leg stay 62, the rear leg stay 68, the footrest 65, and the X-shaped link 71 connecting the pair of front legs 21 and the pair of rear legs 31 is limited only in the pulling direction, and the vehicle body is highly rigid. And stable running can be performed.

  Furthermore, since the front wheel 23 is held by the front wheel caster holder 26 on the inner side in the width direction of the stroller 10 from the axis L of the front leg 21, the front leg 21 is inclined so that the space between the legs spreads downward. Even so, the width of the stroller 10 can be reduced.

  Further, the front leg stay 62, the rear leg stay 68, the footrest 65, and the X-shaped link 71 that connect the pair of left and right front legs 21 and rear legs 31 also function as a reinforcing member for the vehicle body, and can increase the strength of the vehicle body. .

  Next, the operation of the hood 95 will be described in detail.

  First, the operation of assembling the hood lever 80 by connecting the first hood lever 81 and the second hood lever hood lever 91 will be described with reference to FIG.

  When connecting the first hood lever 81 and the second hood lever 91, as shown in FIG. 16, the line connecting the fitting boss 93 and the third restricting portion 95c of the second hood lever 91 and the first hood lever 81 are connected. The first hood lever 81 is disposed with respect to the second hood lever 91 at an intermediate position between the open position (FIG. 15A) and the closed position (FIG. 15B) where the guide groove 82 is substantially parallel. . Thereafter, from the state where the fitting boss 93 of the second hood lever 91 is sandwiched between the leading ends 82a of the guide grooves 82 of the first hood lever 81 (FIG. 16A), the first hood lever 81 is moved to the second hood lever 91. Is pushed toward the second hood lever 91 along the line connecting the fitting boss 93 and the third restricting portion 95c (the direction of the arrow in FIG. 15A). In this case, the first hood lever 81 is deformed so that the width of the guide groove 82 is widened. As a result, the first hood lever 81 is guided by the guide groove 82 of the first hood lever 81 and is fitted into the fitting hole 83 of the first hood lever 81 and the second hole. The fitting boss 93 of the hood lever 91 is fitted (FIG. 16B). In this way, the first hood lever 81 and the second hood lever 91 can be easily connected by simply pushing the first hood lever 81 toward the second hood lever.

  Next, the case where the hood 75 is used will be described.

  As described above, the first hood lever 81 and the second hood lever 91 are connected to each other at the one end 81a, 91a side, and rotate to the first hood bone 77a or the second hood bone 77b at the other end 81c, 91c side, respectively. It is connected freely. Therefore, when the hood lever 80 is in the open position, the first hood bone 77a and the second hood bone 77b are separated from each other, and the hood 75 can be opened. When the hood lever 80 is in the closed position, the first hood bone 77a and the second hood bone 77b approach each other, and the hood 75 can be closed. In this case, as described above, by engaging the positioning projection 84 of the first hood lever 81 and the positioning holes 94a and 94b of the second hood lever 91, the hood lever 80 is set to either the open position or the closed position. Can be fixed. That is, the swing of the first hood bone 77a with respect to the second hood lever 91 can be restricted, and the hood 75 can be kept open or closed.

  When the hood lever 80 is in the open position, the substantially straight portion 85b of the one side surface 85 of the first hood lever 81 is connected to the first restricting portion 95a of the second hood lever 91 as described above. At the same time, the arcuate portion 85a of the one side surface 85 of the first hood lever 81 is disposed close to the third restricting portion 95c (FIG. 15A). In this case, the first restricting portion 95a and the third restricting portion 95c of the second hood lever 91 restrict deformation on one side of the first hood lever 81 so as to widen the width of the guide groove 82. For this reason, even if some force is applied to the hood lever 80 via the hood cloth 76 and the hood bones 77a and 77b, the first hood lever 81 is prevented from coming off from the second hood lever 91. Can do.

  On the other hand, when the hood lever 80 is in the closed position, the substantially straight portion 86b of the other side surface 86 of the first hood lever 81 is connected to the second restricting portion 95b of the second hood lever 91 as described above. At the same time, the arcuate portion 86a of the other side surface 86 of the first hood lever 81 is disposed close to the third restricting portion 95c (FIG. 15B). In this case, the deformation on the other side of the first hood lever 81 that restricts the width of the guide groove 83 is restricted by the second restriction portion 95b and the third restriction portion 95c of the second hood lever 91, and the first hood lever 81 Can be prevented from coming off from the second hood lever 91.

  Next, a case where the hood 75 is closed from the opened state and a case where the hood 75 is opened from the closed state will be described.

  First, when closing the hood 75 from the opened state, the first hood lever 81 and the second hood lever 91 arranged in a substantially straight line are rotated about the fitting boss 93 of the second hood lever 91. Force on. As a result, the positioning projection 84 of the first hood lever 81 is removed from the positioning hole 94a of the second hood lever 91, and the first hood lever 81 and the second hood lever 91 are centered on the fitting boss 93 of the second hood lever 91. Are rotated with respect to each other, and thereafter, the positioning projection 84 of the first hood lever 81 and the positioning hole 94b of the second hood lever 91 are engaged. With such movement of the hood lever 80, the first hood bone 77a swings so as to approach the second hood bone 77b around the connection point to the boss 78. In this way, the hood 75 can be easily closed from the opened state.

  On the other hand, when the hood 75 is opened from the closed state, the bent first hood lever 81 and the second hood lever 91 are rotated around the fitting boss 93 of the second hood lever 91. Apply force to align. As the hood lever 80 is arranged in a straight line, the first hood bone 77 a swings away from the second hood bone 77 b around the connection point to the boss 78. In this way, the hood 75 can be easily opened from the closed state.

  As described above, when the hood 75 is closed from the open state or when the hood 75 is opened from the closed state, the first hood lever 81 and the second hood lever 91 are in the open position (FIG. 15A) and the intermediate position (FIG. 16). 17 (b)) and the state shown in FIG. 17 (b) between the closed position (FIG. 15 (b)) and the intermediate position (FIG. 16 (b)). Become.

  As shown in FIG. 17A, between the open position (FIG. 15A) and the intermediate position (FIG. 16B), the arcuate portion 85a of the one side surface 85 of the first hood lever 81 is 3 It is arranged close to the restricting portion 95c. In this case, the third contact portion 95 c of the second hood lever 91 restricts deformation on one side of the first hood lever 81 so as to widen the width of the guide groove 83. For this reason, when the first hood lever 81 and the second hood lever 91 rotate between the open position (FIG. 15A) and the intermediate position (FIG. 16B), the first hood lever 81 It is possible to prevent the second hood lever 91 from coming off.

  On the other hand, as shown in FIG. 17B, between the closed position (FIG. 15B) and the intermediate position (FIG. 16B), the arc-shaped portion 86a of the other side surface 86 of the first hood lever 81 is provided. Is disposed close to the third restricting portion 95c. In this case, the deformation on the other side of the first hood lever 81 that restricts the width of the guide groove 83 is restricted by the third contact portion 95 c of the second hood lever 91. For this reason, when the first hood lever 81 and the second hood lever 91 rotate between the closed position (FIG. 15B) and the intermediate position (FIG. 16B), the first hood lever 81 It is possible to prevent the second hood lever 91 from coming off.

  As described above, according to the present embodiment, the first hood lever 81 is disposed at an intermediate position with respect to the second hood lever 91 and is pushed toward the second hood lever 91 to The second hood lever 91 can be easily connected. For this reason, since caulking by rivets is not required, it is preferable in appearance and can be manufactured at low cost.

  In addition, the stroller is normally used in either the opened state or the closed state of the hood 75, but the second hood can be used in both the opened position in the opened state and the closed position in the closed state. The restriction portion 95 of the lever 91 restricts deformation of the first hood lever 81 that widens the guide groove 82. Accordingly, it is possible to prevent the first hood lever 81 from being detached from the second hood lever 91 in both cases where the hood 75 is opened and closed.

  Further, when the first hood lever 81 and the second hood lever 91 are between the open position and the intermediate position, and between the closed position and the intermediate position, the first hood lever 81 and the second hood lever 91 are In any case, the restriction of the second hood lever 91 restricts the deformation of the first hood lever 81 so as to widen the guide groove 82. This makes it difficult for the first hood lever 81 to be disengaged from the second hood lever 91 in both cases of closing the hood 75 from the open state and opening it from the closed state.

  Furthermore, since the first hood lever 81 and the second hood lever 91 can be connected without using a rivet, it is possible to prevent the rivet head from being exposed to the appearance of the stroller. Is advantageous. Further, by not using rivets, the number of parts can be reduced and the rivet caulking process can be eliminated, so that the manufacturing cost can be reduced.

  Further, when the stroller 10 is folded, the armrest joint 46 is pressed to the folding position, that is, to the armrest body 41 in the width direction outside by the bending resistance of the guard arm body 57. Thereby, the bending of the guard arm main body 57 bent by folding the stroller 10 can be loosened, and the folding resistance of the stroller 10 can be reduced.

  Furthermore, since it is not necessary to bend the guard arm main body 57 small and tightly, the number of joints of the aggregate 57b of the guard arm main body 57 can be reduced, and a flexible material 57a can be used having high rigidity. Thereby, since the rigidity of the guard arm 56 can be improved, an infant can be protected more safely.

  Furthermore, when the guard arm 56 is attached to the armrest 40 with the stroller 10 deployed, the armrest joint 46 is urged by the compression coil spring 45 and is always disposed at the deployed position, that is, substantially in front of the armrest body 41. . For this reason, it is not necessary for the guardian to adjust the position of the armrest joint 46, or the guard arm 56 can be easily attached to the armrest 40 without deforming the guard arm main body 57.

  In addition, when the stroller 10 is deployed, the front legs 21 and the rear legs 31 are both inclined downward so that the distance between the legs extends in the width direction of the stroller 10. Force acts only in the direction of opening. Thereby, the load applied to the front leg stay 62, the rear leg stay 68, the footrest 65, and the X-shaped link 71 is limited only in the pulling direction, the stroller 10 can be highly rigid, and stable running can be performed. .

  Furthermore, a front wheel 23 is held via a front wheel caster holder 26 at the lower end of the front leg 21 that is greatly inclined so that the distance between the legs spreads downward. The front wheel caster holder 26 bends from the outer side in the width direction of the stroller 10 to the inner side in the width direction, and can hold the front wheel 23 on the inner side in the width direction of the stroller 10 from the axis L of the front leg 21. Can be reduced.

  Furthermore, since such a caster holder 26 is used and the front legs 21 and the rear legs 31 are greatly inclined so that the distance between the legs spreads downward, a sufficient space for arranging links between the legs is secured. be able to.
