The grip member 40, the one-side attachment 31 and the other-side attachment 35 will be described with reference to FIGS. 2 and 9.

The grip member 40 has a grip body 41 and a one-side connection portion 42 connected to one side end portion 41a of the grip body 41. The one-side connecting portion 42 forms one-sided end portion 40a of the grip member 40. As will be understood from FIGS. 2 and 9, the one-side connection portion 42 is detachably connected to the one-side attachment 31. The other end of the grip body 41 forms the other end 40b of the grip member 40. As described above, the other side end portion 40b is non-detachably connected to the other side attachment 35 via the rotating member 50.

The grip body 41 is made of a material that is not easily elastically deformed. The grip body 41 is made of, for example, non-foamed EVA (ethylene vinyl acetate copolymer) or the like. Since the grip body 41 is made of a material that is not easily elastically deformed, even a child with a relatively strong grip can firmly grip the grip member 40.

The one-side attachment 31 and the one-side connection 42 will be described in more detail with reference to FIGS. 3 to 5.

As shown in FIGS. 3 and 4, the one-side attachment 31 has a base portion 31a fixed to the one-side side wall portion 23 and a holding convex portion 31b protruding forward and upward from the base portion 31a. The direction in which the holding convex portion 31b protrudes is the direction D1 along the grip member 40 when the one-side connecting portion 42 of the grip member 40 is attached to the one-side attachment 31. In the illustrated example, the holding convex portion 31b is formed in a columnar shape.

As shown in FIGS. 3 and 5, the one-side connecting portion 42 of the grip member 40 is provided with a holding recess 42a capable of accommodating the holding convex portion 31b. The one-side connection portion 42 and the one-side attachment 31 are connected by accommodating the holding convex portion 31b in the holding recess 42a. Therefore, by moving the one-side connection portion 42 along the projecting direction D1 of the holding convex portion 31b, the one-side connection portion 42 and the one-side attachment 31 can be attached and detached.

In the illustrated example, the one-side attachment 31 and the one-side connection 42 have a maintenance mechanism 45 that keeps the one-side connection 42 connected to the one-side attachment 31. The maintenance mechanism 45 maintains the holding convex portion 31b in a state of being housed in the holding recess 42a. The maintenance mechanism 45 includes a protrusion 46 provided on the holding convex portion 31b and a protrusion receiver 47 formed on the one-side connecting portion 42. Further, the one-side connection portion 42 is provided with a release operation portion 48 for releasing the connection maintenance state between the one-side connection portion 42 and the one-side attachment 31 by the maintenance mechanism 45.

First, the maintenance mechanism 45 will be described. As can be seen from FIGS. 3 and 4, the protrusion 46 projects in the direction D2 intersecting the protrusion direction D1 of the holding convex portion 31b. The protrusion 46 is movable in the holding convex portion 31b along the direction D2, and is urged toward the outside of the holding convex portion 31b along the direction D2. When a force is applied to the protrusion 46 toward the inside of the holding convex portion 31b, the protrusion 46 is buried in the holding convex portion 31b. In the illustrated example, the protrusions 46 are provided on one side and the other side in the width direction of the holding convex portion 31b, respectively.

As shown in FIG. 5, the protrusion receiver 47 is open to the inner surface (the surface defining the holding recess 42a) of the one-side connecting portion 42. More specifically, the protrusion receiver 47 is opened at a position facing the protrusion 46 with the holding protrusion 31b housed in the holding recess 42a. Therefore, when the holding convex portion 31b is accommodated in the holding concave portion 42a, the protrusion 46 fits into the protrusion receiver 47. In the illustrated example, two protrusion receivers 47 are provided corresponding to each protrusion 46. Further, each protrusion receiver 47 extends in a direction corresponding to the protrusion direction D2 of the protrusion 46 in a state where the holding protrusion 31b is housed in the holding recess 42a.

When the holding convex portion 31b is housed in the holding concave portion 42a, the protrusion 46 is pushed toward the inside of the holding convex portion 31b by the surface defining the holding concave portion 42a of the one-side connecting portion 42, and the holding convex portion 31b It is automatically buried inside. Then, when the protrusion 46 reaches the position facing the protrusion 46, the protrusion 46 is automatically fitted into the protrusion 47 by the urging force applied to the protrusion 46. That is, the one-side connecting portion 42 is automatically fixed to the one-side attachment 31 only by inserting the holding convex portion 31b into the holding concave portion 42a. In other words, the one-side connection portion 42 and the one-side attachment 31 are automatically brought into the connection maintenance state by the maintenance mechanism 45.

The release operation unit 48 is used to push the protrusion 46 fitted in the protrusion receiver 47 into the holding convex portion 31b to release the connection maintenance state by the maintenance mechanism 45. In the illustrated example, first, the protrusion receiver 47 described above is a through hole that penetrates the one-side connection portion 42 along the direction D2. Then, at least a part of the release operation portion 48 is housed in the protrusion receiver 47 from the outside of the one-side connection portion 42. By pushing the release operation portion 48 from the outside to the inside of the one-side connection portion 42, the protrusion 46 can be pushed into the holding convex portion 31b to release the connection maintenance state by the maintenance mechanism 45. In the illustrated example, the release operation unit 48 is provided on each of the two protrusion receivers 47.

Next, with reference to FIGS. 6 to 8, the other side end portion 40b of the grip member 40, the other side attachment 35, and the rotating member 50 will be described in more detail.

As shown in FIGS. 6 to 8, the other side attachment 35 has a base portion 35a fixed to the other side side wall portion 24 and a columnar first shaft portion 35b protruding forward and upward from the base portion 35a. The first shaft portion 35b extends in the direction D1 along the grip member 40 in a state where the one-side connecting portion 42 of the grip member 40 is attached to the one-side attachment 31. From the outer peripheral surface of the first shaft portion 35b, the protruding portion 35c extends in a direction intersecting the direction D1.

A rotating member 50 is non-detachably connected to the first shaft portion 35b. The rotating member 50 is rotatable relative to the other side attachment 35 (and therefore to the seat body 20). The rotating member 50 is rotatable relative to the other side fixture 35 with the center line of the columnar first shaft portion 35b as the first rotating axis Ax and the center line of the first rotating axis Ax as the center. The first rotation axis Ax extends along the above-mentioned direction D1. As is well shown in FIGS. 6 and 8, the rotating member 50 has a columnar second shaft portion 50a at the upper end portion thereof, which connects the other side end portion 40b of the grip member 40. The second shaft portion 50a extends in a direction non-parallel to the first rotation axis Ax.

In the illustrated example, the rotating member 50 has a first component 51 supported by the other side fixture 35 and a second component 52 having a second shaft portion 50a and fixed to the first component 51. .. The first component 51 has a first portion 51a supported from the rear lower part by the other side attachment 35, and a second portion 51b to which the other side end portion 40b of the grip member 40 is connected. The first portion 51a has a hole through which the first shaft portion 35b is inserted. The second portion 51b supports the other side end portion 40b of the grip member 40 from one side in the rear lower portion and the longitudinal direction of the second shaft portion 50a. Further, the second component 52 has a first portion 52a formed in an annular shape through which the first shaft portion 35b is inserted, and a second portion 52b formed with the second shaft portion 50a. The second portion 52b supports the other side end portion 40b of the grip member 40 from the rear lower side and the other side in the longitudinal direction of the second shaft portion 50a. The second shaft portion 50a extends from the second portion 52b of the second component 52 toward the second portion 51b of the first component 51. The first component 51 and the second component 52 cannot be removed from the first shaft portion 35b due to the protruding portion 35c protruding from the first shaft portion 35b.

As is well shown in FIGS. 7 and 8, the other end 40b of the grip member 40 is provided with a shaft hole 40c extending in a direction non-parallel to the extending direction of the grip member 40. The second shaft portion 50a of the rotating member 50 is inserted into the shaft hole 40c. As a result, the grip member 40 has a second rotation axis with the center line of the columnar second shaft portion 50a as the second rotation axis Bx in a state where the one-side end portion 40a is removed from the one-side attachment 31. It is rotatable relative to the rotating member 50 (and thus to the seat body 20) about Bx. Further, as described above, since the rotating member 50 can rotate relative to the seat body 20 about the first rotation axis Ax, the grip member 40 can rotate with respect to the seat body 20 about the first rotation axis Ax. It is relatively rotatable. That is, the grip member 40 can rotate relative to the seat body 20 about two rotation axes Ax and Bx that are not parallel to each other. Thereby, the posture of the grip member 40 with respect to the seat body 20 can be changed in various ways. Further, even if the grip member 40 is made of a material that is not easily elastically deformed, such as non-foamed EVA (ethylene vinyl acetate copolymer), the one-side end portion 40a of the grip member 40 can be easily removed from the one-side attachment 31. Can be done.

In the illustrated example, the first rotation axis Ax and the second rotation axis Bx are orthogonal to each other. As a result, the posture of the grip member 40 with respect to the seat body 20 can be efficiently changed. Further, in a state where the one-side end portion 40a is connected to the one-side attachment 31, the second rotation axis Bx is along the tip 24a of the other-side side wall portion 24 at the position where the other-side attachment 35 is provided. .. As a result, when the one-side end 40a of the grip member 40 is removed from the one-side attachment 31 and the grip member 40 is relatively rotated with respect to the seat body 20 about the second rotation axis Bx, a force for relative rotation. Can be efficiently added to the grip member 40.

Here, a method of operating the grip member 40 by the child seat 10 of the present embodiment will be described. First, an operation method for moving the grip member 40 from the position shown in FIG. 2 to the position shown in FIG. 11 via the positions shown in FIGS. 9 and 10 will be described.

First, when the grip member 40 is in the state shown in FIG. 3, the one-side connection portion 42 of the grip member 40 is connected to the one-side attachment 31. More specifically, the holding convex portion 31b of the one-side attachment 31 is housed in the holding recess 42a of the one-side connecting portion 42. Further, the protrusion 46 of the holding convex portion 31b is fitted into the protrusion receiving 47 of the one-side connecting portion 42. When moving the grip member 40 from the position shown in FIG. 3 to the position shown in FIG. 9, first, the release operation portion 48 is pushed inside the one-side connecting portion 42, and the protrusion 46 is buried in the holding convex portion 31b. While maintaining this state, the one-side connection portion 42 is lifted along the extending direction D1 of the one-side connection portion 42, and the one-side connection portion is removed from the one-side attachment 31. At this time, the grip member 40 is rotated relative to the seat body 20 about the second rotation axis Bx. After that, the grip member 40 is further rotated relative to the seat body 20 about the second rotation axis Bx, and is moved to the position shown in FIG.

Next, the grip member 40 is rotated relative to the seat body 20 about the first rotation axis Ax, and the posture of the grip member 40 with respect to the seat body 20 is set to the posture shown in FIG.
