In addition, the stroller 10 may further include components not shown, such as a storage basket and a lid.

First, with reference to the illustrated example, the stroller body 20 will be described. As shown in FIGS. 1 to 4 , the baby carriage body 20 has a substantially symmetrical structure centered on a central plane in the width direction along the front-rear direction as a whole. The stroller body 20 has wheels 33 and 38 and a handle 40, and is a handcart that an operator can push by gripping the handle 40. As shown in FIG. 4 , the stroller body 20 includes a handle 40, a front leg 30 and a rear leg 35 including wheels 33 and 38 at the lower end, and a first - Third link members 21 to 23 are further included as main components. These components are capable of relative operation in order to enable the folding operation of the stroller body 20 .

As shown in FIGS. 2 and 4 , the first link member 21 is located above the front legs 30 and the rear legs 35 and extends in the front-back direction. A pair of 1st link members 21 are spaced apart from each other in the width direction, and are provided. The 1st link member 21 is formed as a resin molded product, for example.

As shown in FIGS. 2 and 4 , the front leg 30 is connected to the first link member 21 . Corresponding to the pair of first link members 21, a pair of front legs 30 are spaced apart in the width direction and provided. That is, each front leg 30 is connected to the first link member 21 on the corresponding side in the width direction. Front leg 30 is connected to the front part of the 1st link member 21, especially the front part of the 1st link member 21. The front leg 30 has a longitudinal direction. The front leg 30 is inclined with respect to the up-down direction and the front-back direction so that the longitudinal direction of the front leg 30 faces downward toward the front. In the illustrated example, the front leg 30 is connected to the first link member 21 at its upper end. The front leg 30 is connected to the first link member 21 so as to be able to swing. In other words, the first link member 21 and the front leg 30 can rotate around an axis along the width direction.

A pair of holding members 50 are spaced apart in the width direction and are arranged. As shown in FIG. 1 , the seat 60 is held 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 53 that supports the supported portion 63 provided on the seat 60 . The support portion 53 may be formed as an upwardly-opening accommodation hole or an upwardly protruding insertion portion. Further, the supported portion 63 may be configured as a downwardly projecting insertion portion insertable into the receiving hole of the support portion 53 or a downwardly opening receiving hole insertable into the insertion portion of the support portion 53 . In the illustrated example, the holding member 50 has a receiving hole formed in the supporting surface 52 facing upward as a supporting portion 53 . The support surface 52 extends in the front-back direction. In other words, an accommodation hole as the support portion 53 is formed in the central portion of the support surface 52 extending in the front-back direction. The support surface 52 faces upward, and the accommodating hole forming the support portion 53 is open upward.

On the other hand, in the seat 60, a pair of base portions 61 disposed apart from each other in the width direction have a supported portion 63. That is, corresponding to each base part 61, respectively, a pair of holding members 50 are spaced apart in the width direction and are provided. The base portion 61 has a supported surface 62 facing downward. The supported surface 62 extends in the front-back direction corresponding to the support surface 52 . An insertion portion constituting the supported portion 63 protrudes downward from the central portion of the supported surface 62 in the front-back direction.

According to the configuration of the support portion 53 and the supported portion 63, the seat 60 is lowered onto the stroller body 20 from above in the vertical direction, and the seat 60 is secured to the stroller via the holding member 50. It becomes possible to hold in the main body 20. 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 supporting portions 53 of the corresponding holding members 50. . Then, the supported surface 62 of the base portion 61 comes into contact with the supporting surface 52 of the holding member 50, so that the seat 60 is held on the stroller body 20. With the seat 60 being held by the stroller body 20, since the support portion 53 engages with the supported portion 63, the relative movement of the seat 60 relative to the stroller body 20 in the horizontal direction this is regulated

In addition, the pair of holding members 50 and the pair of base portions 61 are spaced apart in the width direction and are disposed. Therefore, in a state in which the seat 60 is held by the stroller body 20, displacement due to relative rotation of the seat 60 and the stroller body 20 centered on the axis along the front-back direction, and along the vertical direction Displacement due to relative rotation of the seat 60 and the stroller body 20 centered on the axis can be effectively controlled. In addition to this, as shown in FIGS. 6 and 7 , the support surface 52 extends before and after the support portion 53, and the supported surface 62 extends before and after the supported portion 63. Therefore, in a state in which the seat 60 is held by the stroller body 20, displacement due to relative rotation of the seat 60 and the stroller body 20 centered on the axis along the width direction can be effectively regulated. . In view of the above, the seat 60 can be stably held by the seat 60 provided in the stroller body 20 .

In the illustrated example, the stroller body 20 has a link structure for enabling a folding operation. These link structures include a pair of structures symmetrical about a center plane in the width direction spaced apart in the width direction. And the pair of holding members 50 are arrange|positioned between a pair of components, and the seat 60 is held between a pair of components. Specifically, the seat 60 is between a pair of first link members 21, between a pair of front legs 30, between a pair of rear legs 35, and between a pair of handle extensions 42. is maintained on Such an arrangement of the seat 60 makes it possible to avoid interference with components of the stroller body 20 . That is, the holding member 50 can hold the seat 60 by separating the seat 60 from the stroller body 20 . Therefore, as shown in FIG. 9, the direction of the seat 60 held by the stroller body 20 through the holding member 50 can be changed. Accordingly, by simply changing the direction of the seat 60, the infant shown in FIG. 9(a) faces the forward direction of the stroller 10, and the infant shown in FIG. It becomes possible to switch the face-to-face state of facing the manipulator (guardian) of (10). In addition, such an arrangement of the seat 60 can avoid interference between the stroller body 20 and the seat 60 during the folding operation. Therefore, as shown in FIG. 3, it becomes possible to fold the stroller main body 20 with the seat 60 held. In the illustrated baby carriage 10, it is possible to fold the baby carriage 10 while the seat 60 is held by the baby carriage body 20 in either of the face-to-face state and the rear face state.

In addition, the baby carriage 10 has a fixing mechanism 90 for holding the seat 60 in a state supported by the baby carriage body 20 . The fixing mechanism 90 maintains the supported portion 63 in a fixed state in which the supported portion 63 is supported or engaged with the support portion 53 . In the illustrated example, the fixing mechanism 90 includes a protrusion 64 provided on the supported portion 63 and a protrusion accommodating portion 54 provided on the holding member 50 . In addition, the holding member 50 is provided with an operation unit 55 for releasing the fixed state by the fixing mechanism 90 .

As shown in FIGS. 6 and 10 , the protruding accommodating portion 54 is formed in a wall portion on the inner side in the width direction among wall portions forming the support portion (accommodating hole) 53 of the holding member 50 . On the other hand, as shown in FIG. 10 , the protrusion 64 is accommodated in a space 63a extending in the width direction formed inside the supported portion 63 . The projection 64 is pressed inward in the width direction from the supported portion 63 by a pressing means 64s disposed between the projection 64 and the wall surface 63b partitioning the space 63a. In the illustrated example, the biasing means 64s is a spring. Since the lower side surface of the protrusion 64 is inclined, when the supported part 63 is inserted into the support part 53, it is automatically buried in the space 63a of the supported part 63. Then, when the projection 64 reaches a position facing the projection accommodating portion 54, it is fitted into the projection accommodating portion 54 by the pressing force from the pressing means 64s. Therefore, when the seat 60 is moved downward by inserting the supported portion 63 into the support portion 53, the seat 60 is automatically fixed to the holding member 50.

In the stroller 10 having such a fixing mechanism 90, after inserting the supported portion 63 of the seat 60 into the support portion 53 of the stroller body 20, when an infant is seated on the seat 60, The seat 60 is automatically fixed relative to the retaining member 50 . That is, the seat 60 is pushed downward by the weight of the infant, and the protrusion 64 of the supported portion 63 moves to a position facing the protrusion accommodating portion 54 of the support portion 53, and the protrusion accommodating portion ( 54) is inserted. Therefore, it is prevented that, when an infant is put on the stroller 10, the stroller 10 starts running without the seat 60 being properly fixed to the stroller body 20. This is convenient in terms of the safety of the stroller 10 .

The operating portion 55 is provided at a position facing the projection accommodating portion 54 on the inner surface of the holding member 50 in the width direction. The operation unit 55 is accommodated in an operation unit accommodating portion 55a formed at a position facing the projection accommodating portion 54 on the inner side of the holding member 50 in the width direction, and extends within the operation unit accommodating portion 55a in the width direction. can be moved to As for the operation part 55, the part protrudes inward in the width direction from the operation part accommodating part 55a. The projection 64 fitted in the projection accommodating portion 54 can be pushed out of the projection accommodating portion 54 by pushing the operating portion 55 outward in the width direction. That is, by operating the operation unit 55, the fixation by the fixing mechanism 90 can be released. The operation unit 55 may be provided in the stroller body 20 .

In addition, the projection 64 described above may be provided on the holding member 50, and the projection accommodating portion 54 may be provided on the supported portion 63. In this case, the protrusion 64 is pressed toward the side facing the supported portion 63 . In addition, the operation unit 55 may act to withdraw the projection 64 accommodated in the projection accommodating portion 54 from the projection accommodating portion 54 .

In the stroller 10 including the above-described support portion 53, the supported portion 63, and the fixing mechanism 90, when the seat 60 is separated from the stroller body 20, the fixing mechanism 90 An operation to release the fixed state (an operation to push the control unit 55 in the illustrated example) and an operation to separate the supported portion 63 from the support portion 53 by lifting the seat 60 are required. By requiring a plurality of operations in this way, it is prevented that the seat 60 comes off unintentionally from the stroller body 20.

In addition, since the control unit 55 is provided not on the seat 60 but on the holding member 50 or the stroller body 20, the seat 60 is operated while releasing the fixed state of the seat 60 by operating the control unit 55. It becomes difficult to lift. This makes it difficult for the seat 60 to be separated from the stroller body 20 while the infant is seated. Therefore, it is convenient in terms of the safety of the stroller 10.

In addition, since the operation unit 55 protrudes into a space surrounded by the front legs 30 and the rear legs 35 of the stroller body 20, unintentional operation of the operation unit 55 is prevented. For example, it is prevented that the operation unit 55 comes into contact with objects present around the baby carriage 10 and is operated unintentionally.

In addition, as described above, to prevent the seat 60 from being separated from the stroller body 20 while the infant is seated, the stroller 10 lifts the seat 60 while operating the operation unit 55. is configured to be difficult. However, it is preferable that the separation work of the seat 60 in a state where an infant is not seated in the seat 60 is easy. In consideration of this point, the baby carriage 10 is provided with a pressing means 95 to assist in the separation operation.

Referring to Fig. 10, the pressing means 95 will be described. The pressing means 95 is provided between the support part 53 and the supported part 63, and acts to separate the seat 60 from the stroller body 20. In the illustrated example, the pressing means 95 has a spring 96 and a downward protrusion 97 pressed downward by the spring 96 . The spring 96 and the lower projection 97 are accommodated in a space 63c extending in the vertical direction formed in the supported portion 63. The spring 96 is disposed between the lower projection 97 and the wall surface 63d that divides the space 63c. The lower end of the lower projection 97 protrudes from the lower end of the supported portion 63 and is in contact with the lower end surface of the support portion 53 . This pressing means 95 can press the supported portion 63 upward.

Further, the pressing force of the pressing means 95 can lift the seat 60 in a state where an infant is not seated in the seat 60, but the seat 60 is lifted in a state where an infant is seated in the seat 60. It is adjusted so that it cannot be lifted.

When an infant is not seated in the seat 60, the pressing means 95 pushes the seat 60 upward when the operation unit 55 is operated and the fixed state by the fixing mechanism 90 is released. . Then, the seat 60 is held in a position where the protrusion 64 of the fixing mechanism 90 does not face the protrusion accommodating portion 54 . That is, the fixed state by the fixing mechanism 90 is maintained in a released state. Therefore, when the operator of the stroller 10 separates the seat 60, the operation of the operation unit 55 (that is, the operation of releasing the fixed state by the fixing mechanism 90) and the operation of lifting the seat 60 There is no need to perform the actions simultaneously. This facilitates the removal work of the seat 60.

In addition, since the protrusion 64 of the fixing mechanism 90 is accommodated in the protrusion accommodating portion 54 while the fixed state is maintained by the fixing mechanism 90, the pressing force of the pressing means 95 applies to the seat. (60) is prevented from being pushed up. Further, as described above, even when an infant is seated on the seat 60, the pressing force of the pressing means 95 prevents the seat 60 from being pushed up. Therefore, the pressing means 95 operates on the supported portion 63 only when no infant is seated on the seat 60 and the operation unit 55 is operated to release the fixed state by the fixing mechanism 90. By lifting the upward, the seat 60 can be spaced apart from the stroller body 20.

In the illustrated example, the stroller 10 is provided with two fixing mechanisms 90 . In order to separate the seat 60 from the stroller body 20, it is necessary to simultaneously release the fixed state by the two fixing mechanisms 90. Both hands are required to release both fixing mechanisms 90 simultaneously. This prevents the seat 60 from being separated from the stroller body 20 in a state in which an infant is seated on the seat 60 . That is, even when an infant is seated in the seat 60, if the seat 60 is lifted while the fixing mechanism 90 is continuously released by operating the control unit 55, the seat 60 is moved to the stroller body 20. ) can be separated from However, since both hands are required to release the fixing mechanism 90, it becomes significantly difficult to lift the seat 60 by one person while releasing the fixing mechanism 90. This effectively improves the safety of the stroller 10.

Next, the attachment structure and attachment position of the holding member 50 to the stroller body 20 will be described.

In this embodiment, as shown in FIG. 7 , each holding member 50 is connected to a plurality of connection positions JPX and JPY spaced apart from each other of the baby carriage body 20 . As a result, in the illustrated example, each holding member 50 is fixed to the baby carriage body 20 and is stably held by the baby carriage body 20 . Moreover, the support part 53 of the holding member 50 is located above one connection position JPX of the stroller body 20. Therefore, the weight of the seat 60 held by the holding member 50 can be stably and efficiently supported by the stroller body 20 . Thus, rattling of the holding member 50 relative to the stroller body 20 can be effectively reduced. In addition, since it is not necessary to increase the size of the holding member 50 or to provide a large number of holding members 50, the design of the stroller 10 can be improved.

In the illustrated example, each holding member 50 is first connected to the handle extension 42 on the rotation axis AR1 of the second link member 22 and the handle extension 42 . As a specific configuration, as shown in FIGS. 6 and 7 , each holding member 50 is connected to a main shaft member 25 that connects the second link member 22 and the handle extension 42 so as to be able to rotate. there is. That is, in the illustrated example, the first connecting position JPX of the holding member 50 to the stroller body 20 becomes the main shaft member 25 . The main shaft member 25 passes through the holding member 50 . The main shaft member 25 also passes through the second link member 22 and the third link member 23 . Therefore, the holding member 50 is connected not only to the handle extension 42 of the handle 40, but also to the second link member 22 and furthermore to the third link member 23 via the main shaft member 25. have done

In addition, each holding member 50 is connected to the reinforcing connecting member 45 of the handle 40 . The reinforcing connecting member 45 is connected to the handle extension 42 as a part of the handle 40 . That is, in the illustrated example, the second connecting position JPY of the holding member 50 to the stroller body 20 becomes the reinforcing connecting member 45 . As shown in FIG. 7 , the holding member 50 has a through hole 56 through which the reinforcing connecting member 45 passes. The cross-sectional shape of the reinforcing connecting member 45 is slightly flattened from a circular shape. The through hole 56 of the holding member 50 is also slightly flat. Therefore, when the reinforcing connecting member 45 penetrates the through hole 56 of the holding member 50, the rotation of the holding member 50 relative to the baby carriage body 20 in the axial line along the width direction is restricted. .

In such a baby carriage 10, the first connecting position JPX of the holding member 50 to the baby carriage body 20 is the main shaft member 25, and is connected to the lower portion of the holding member 50. And, as shown in FIG. 7, the support part 53 of the holding member 50 is arrange|positioned at the position shifted upward along the vertical direction from the main shaft member 25. Therefore, the weight of the seat 60 held by the holding member 50 is efficiently transferred by the stroller body 20 without increasing the size of the holding member 50 or providing a large number of holding members 50. can sustain

Further, the second connecting position JPY of the holding member 50 to the baby carriage body 20 is connected to the rear portion of the holding member 50 as a reinforcing connecting member 45 . Therefore, as shown in FIG. 7, the holding member 50 faces the reinforcing connecting member 45 from the front along the front-back direction. And the support part 53 of the holding member 50 is arrange|positioned at the position shifted forward from the reinforcing connection member 45 along the front-back direction. Therefore, the baby carriage body 20 can efficiently and stably receive the inertial force from the seat 60 at the time of moving forward via the holding member 50 . Accordingly, it is possible to suppress the rattling of the holding member 50 relative to the stroller body 20 more effectively.

In addition, when the distance between the two connection positions JPX and JPY of the baby carriage body 20 is close, the holding member 50 tends to rattle with respect to the baby carriage body 20 . On the other hand, if the insertion length IL along the up-down direction between the support portion 53 of the holding member 50 and the supported portion 63 of the seat 60 is long, the seat 60 relative to the holding member 50 may be rattled. It can effectively suppress turbulence. On the other hand, if this insertion length IL is long, a large force is applied to the holding member 50, and rattling of the holding member 50 relative to the stroller body 20 tends to occur. In this regard, as shown in FIG. 7 , the separation distance D between the two connecting positions JPX and JPY is the support portion 53 of the holding member 50 and the supported portion 63 of the seat 60 It is longer than the insertion length (IL) in the vertical direction of . Also by this, it is possible to suppress the rattling of the holding member 50 relative to the stroller body 20 more effectively.

In addition to this, in order to efficiently support the force applied to the holding member 50 by the baby carriage body 20, from the support portion 53 of the holding member 50 to the connection position (JPX, JPY) to the baby carriage body 20 It is effective that the distances D1 and D2 are shortened. The distance from the support part 53 of the holding member 50 to any one connection position (JPX, JPY), in particular, the shortest distance between the support part 53 of the holding member 50 and any one connection position, the support part ( 53) and the insertion length IL of the supported portion 63 in the vertical direction is preferably shorter. In the illustrated example, the shortest distance from the support portion 53 of the holding member 50 to any connecting position (JPX, JPY) is the insertion length of the support portion 53 and the supported portion 63 in the vertical direction. It is shorter than (IL). That is, as shown in FIG. 7 , the shortest distance D1 between the support portion 53 and the first connection position JPX is the insertion length IL of the support portion 53 and the supported portion 63 in the vertical direction. It is shorter, and the shortest distance D1 between the support part 53 and the second connection position JPY is shorter than the insertion length IL of the support part 53 and the supported part 63 in the vertical direction. there is.

In particular, in the illustrated example, the distance D1 along the vertical direction from the support part 53 to the first connection position JPX located below the support part 53 is It is shorter than the insertion length (IL) in the vertical direction of . Therefore, the baby carriage body 20 can support the weight of the seat 60 held by the holding member 50 efficiently in the first connection position JPX. In addition, the distance D2 along the front-back direction from the support part 53 to the second connection position JPY located behind the support part 53 is the vertical direction of the support part 53 and the supported part 63. It is shorter than the insertion length (IL). Therefore, the baby carriage body 20 can efficiently and stably receive the inertial force from the seat 60 during forward movement via the holding member 50 in the second connecting position JPY.

As a result of the above mounting structure, the support portion 53 of the holding member 50 is attached to the first link member 21, the handle extension portion 42 of the handle 40, and the rear leg 35, as shown in FIG. located in the area surrounded by That is, the support portion 53 of the holding member 50 is approximately located at the center of the stroller body 20 . Thereby, the seat 60 can be stably and efficiently supported.

By the way, as described above, the first connecting position JPX of the holding member 50 to the stroller body 20 is the main shaft member 25, and the second connecting position JPY is the reinforcing connecting member 45 is made up of Accordingly, the holding member 50 is connected to the second link member 22 , the third link member 23 , and the handle extension portion 42 of the handle 40 via the main shaft member 25 . Further, the holding member 50 is connected to the handle extension portion 42 of the handle 40 via a reinforcing connecting member 45 . That is, the holding members 50 are connected to different positions on the handle extension 42 of the handle 40 through different routes. For this reason, the holding member 50 is fixed with respect to the handle 40 . Here, “fixed with respect to the handle 40” means not only directly connected to the handle, but also indirectly connected to the handle and another member, and maintaining a constant relative position with the handle 40 Including what is

As described above, in the deployed state shown in FIG. 2, the handle 40 is placed in a high position. On the other hand, in the folded state shown in Fig. 3, the handle 40 is disposed in a low position. By fixing the holding member 50 to the handle 40, the seat 60 is placed at a high position in the vertical direction in the deployed state. By arranging the seat 60 at a high position, infants on the seat 60 can effectively avoid the influence of heat and dust from the ground. In addition, since the seating surface 65A of the seat 60 is high, it is possible to easily and stably lift an infant. On the other hand, in the folded state, as shown in Fig. 3, the handle 40 is disposed at a low position. Along with this handle 40, the seat 60 is also placed in a low position. Therefore, the folding dimension of the stroller 10 can be miniaturized.

Also, the orientation of the retaining member 50 is also constant with respect to the handle 40 . Therefore, during the folding operation, the seat 60 held by the holding member 50 does not generate a large moment. On the other hand, the weight of the seat 60 presses down the handle 40. That is, the weight of the seat 60 assists the folding operation of lowering the handle 40 . Therefore, the folding operation can be performed smoothly.

Further, in the illustrated example, when viewed from the side shown in FIG. 2, the seat surface 65A formed by the seat 60 is at the connection position JP1 between the first link member 21 and the front leg 30. It is located higher up. Similarly, when viewed from the side shown in FIG. 2, the rocking axis AS1 of the backrest portion 70 with respect to the seat portion 65 is at the connection position JP2 between the first link member 21 and the rear leg 35. It is located higher up. 2, the rocking axis AS1 of the back portion 70 with respect to the seat portion 65 is higher than the connection position JP4 of the handle 40 and the second link member 22. is located on In addition, when viewed from the side shown in FIG. 2 , the rocking axis AS2 of the side frame member 73 relative to the side support 72 is located above the first link member 21 . Moreover, the rocking axis AS2 of the side frame material 73 with respect to the side support part 72 is located above the connection position JP1 of the 1st link member 21 and the front leg 30, and 1st link It is located above the connection position JP2 of the member 21 and the back leg 35, and is located above the connection position JP3 of the 1st link member 21 and the handle 40. In the specific example shown in this way, since the seat 60 is held at a high position when the stroller 10 is deployed, it is possible to easily carry out lifting and reclining operations of infants, opening and closing operations of covers, and the like. On the other hand, as described above, since the seat 60 is fixed relative to the handle 40, the folding dimension of the stroller 10 can be sufficiently miniaturized.

The stroller 10 configured as described above is driven by an operator (user, guardian) holding the handle connecting portion 43 of the handle 40 and pushing the handle 40 . In this stroller 10, as shown in FIG. 9, the direction of the seat 60 is changed, and the holding member 50 can hold the seat 60. In other words, it is not necessary to rock the handle 40 when switching between the back state and the facing state. Accordingly, the possibility that the handle 40 interferes with other components of the stroller 10 is reduced. For this reason, the reinforcing connection member 45 which connects the pair of handle extension parts 42, which was thought to be impossible to attach, can also be attached to the handle main body 41.

In the illustrated example, the handle 40, in addition to the handle body 41 having a pair of handle extensions 42 and a handle connecting portion 43 connecting the ends of the pair of handle extensions 42, It further has a reinforcing connection member 45 connecting the pair of handle extension parts 42 at a position separated from the handle connection part 43. The handle connecting portion 43 effectively reinforces the handle body 41, so that the rigidity of the handle 40 is improved. As a result, when force is applied to the handle connecting portion 43 serving as the upper end of the handle 40, deformation of the handle 40 can be effectively suppressed. As a result, the force applied to the handle 40 is effectively used for driving of the stroller 10 . In addition, the operator can also fully grasp the state of the running surface and the like through the handle 40 . From these points, the maneuverability of the stroller 10 can be remarkably improved.

In addition to this, in the illustrated baby carriage 10, the member connected between both ends of the reinforcing connecting member 45 in the width direction is displaced from the connecting position between the reinforcing connecting member 45 and the handle extension 42. , it is connected to the handle extension part 42. More specifically, the member connected between both ends of the reinforcing connecting member 45 in the width direction includes the holding member 50 . As a result, the rigidity of the handle 40 can be further improved. In particular, the holding member 50 has a function of holding the seat 60, and therefore, the rigidity of the handle 40 can be improved efficiently without increasing the number of parts.

In addition, this member connected between both ends of the reinforcing connecting member 45 in the width direction is on the rotation axis AR1 of the second link member 22 and the handle extension 42, the handle extension ( 42) is connected. More specifically, the member connected between both ends of the reinforcing connecting member 45 in the width direction further includes the main shaft member 25 . In this stroller 10, the rigidity of the handle can be further improved. In particular, the rigidity of the main shaft member 25 may be improved, and thus, the folding operation and the unfolding operation may be smoothed.

According to one embodiment described above, the baby carriage 10 is supported by the baby carriage body 20, the holding member 50 provided on the baby carriage body 20, and the support portion 53 provided on the holding member 50. It has a supported portion 63 to be, and is provided with a seat 60 detachable from the stroller body 20 via the holding member 50. The stroller 10 is further provided with a fixing mechanism 90 for maintaining the supported portion 63 in a fixed state supported by the support portion 53, and an operation unit 55 for releasing the fixed state by the fixing mechanism 90. ) is provided on at least one of the baby carriage body 20 and the holding member 50. According to such a stroller 10, in order to separate the seat 60 from the stroller body 20, it is necessary to operate the operation unit 55. Therefore, there is little possibility that the seat 60 will come off from the baby carriage body 20 unintentionally. In addition, since the operation unit 55 is provided not on the seat 60 but on the stroller body 20 or the holding member 50, the seat 60 is separated from the stroller body 20 while operating the operation unit 55. it is difficult Therefore, it is difficult to separate the seat 60 from the stroller body 20 while the infant is seated. This is convenient in terms of the safety of the stroller 10 .

In the above-described specific example, the fixing mechanism 90 is provided on the holding member 50 or the supported portion 63, and is pressed toward the side facing the supported portion 63 or the holding member 50. 64, and a protrusion accommodating portion 54 provided on the supported portion 63 or the holding member 50 and accommodating the protrusion 64. And the operation part 55 pushes out the projection 64 accommodated in the projection accommodating part 54 from the projection accommodating part 54, or withdraws it.
