As shown in FIGS. 3 and 4 , the one-side end support member 31 has a base portion 31a fixed to the one-side side wall portion 23 and a holding protrusion 31b protruding forward and upward from the base portion 31a. The direction in which the holding protrusions 31 b protrude is the direction D1 along which the handle member 40 follows when the one-side connecting portion 42 of the handle member 40 is attached to the one-side end portion supporting member 31 . In the illustrated example, the holding protrusion 31b is formed in a cylindrical shape.

As shown in FIGS. 3 and 5 , a holding recess 42 a capable of accommodating the holding convex portion 31 b is provided on one side of the connecting portion 42 of the handle member 40 . The one-side connecting portion 42 is connected to the one-side end portion support member 31 by accommodating the holding convex portion 31b in the holding concave portion 42a. Therefore, the one-side connecting portion 42 can be attached to and detached from the one-side end portion support member 31 by moving the one-side connecting portion 42 in the protruding direction D1 of the holding projection portion 31b.

In the example shown in the figure, the one-side end support member 31 and the one-side connecting portion 42 have a maintaining mechanism 45 that maintains a state in which the one-side connecting portion 42 and the one-side end portion support member 31 are connected. The holding mechanism 45 maintains a state in which the holding convex portion 31b is accommodated in the holding concave portion 42a. The holding mechanism 45 includes a protrusion 46 provided on the holding convex portion 31 b and a protrusion receiving member 47 formed on the one-side connecting portion 42 . Further, on one side The 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 end portion support member 31 by the maintaining mechanism 45 .

First, the maintenance mechanism 45 will be described. As can be understood from FIGS. 3 and 4 , the protrusions 46 protrude in a direction D2 intersecting with the protruding direction D1 of the holding convex portion 31b. The protrusion 46 can move in the above-mentioned direction D2 in the holding convex portion 31b, and is urged toward the outer side of the holding convex portion 31b in the above-mentioned direction D2. When a force toward the inside of the holding convex portion 31b is applied to the protrusion 46, the protrusion 46 is hidden in the holding convex portion 31b. In the example shown in the figure, the protrusions 46 are provided on one side and the other side in the width direction of the holding protrusion 31b, respectively.

As shown in FIG. 5, the protrusion receiving member 47 is opened on the inner surface of the one-side connecting portion 42 (the surface defining the holding recess 42a). More specifically, the protrusion receiver 47 is provided at a position facing the protrusion 46 in a state where the holding protrusion 31b is accommodated in the holding recess 42a. Therefore, when the holding convex portion 31 b is accommodated in the holding concave portion 42 a, the protrusion 46 is fitted into the protrusion receiving member 47 . In the example shown in the figure, two protrusion receivers 47 are provided corresponding to each protrusion 46 . In addition, each protrusion receiver 47 extends in a direction that matches the protruding direction D2 of the protrusion 46 in a state where the holding convex portion 31b is accommodated in the holding concave portion 42a.

When the holding convex portion 31b is accommodated in the holding concave portion 42a, the projection 46 is automatically hidden in the holding convex portion 31b by being pressed 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. Then, when the protrusion receiver 47 reaches a position facing the protrusion 46 , the protrusion 46 is automatically fitted into the protrusion receiver 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 end portion support member 31 by simply 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 end portion support member 31 are automatically in the connection maintaining state by the maintaining mechanism 45 .

The release operation part 48 is used in order to press the protrusion 46 fitted in the protrusion receiver 47 into the holding convex part 31b and release the connection maintained state by the holding mechanism 45 . In the illustrated example, the first First, the protrusion receiving member 47 is a through hole passing through the one-side connecting portion 42 in the direction D2. And at least a part of the release operation part 48 is accommodated in the protrusion receiver 47 from the outer side of the one side connection part 42. As shown in FIG. By pushing the release operation portion 48 from the outside to the inside of the one-side connecting portion 42 , the protrusion 46 is pushed into the holding convex portion 31 b , and the connection maintaining state by the maintaining mechanism 45 can be released. In the example shown in the figure, the release operation parts 48 are respectively provided in the two projection receivers 47 .

Next, referring to FIGS. 6 to 8 , the other end portion 40b of the handle member 40 , the other end portion support member 35 , and the rotating member 50 will be described in more detail.

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

The rotation member 50 is connected to the 1st shaft part 35b so that attachment or detachment is not possible. The rotating member 50 is relatively rotatable with respect to the other end support member 35 (ie, with respect to the seat body 20 ). The rotation member 50 is rotatable relative to the other end support member 35 with the center line of the cylindrical first shaft portion 35b as the first rotation axis Ax and the first rotation axis Ax as the center. The first rotation axis Ax extends in the aforementioned direction D1. As clearly shown in FIGS. 6 and 8 , the rotating member 50 has a cylindrical second shaft portion 50 a connected to the other end portion 40 b of the handle member 40 at the upper end portion thereof. The second shaft portion 50a extends in a direction not parallel to the first rotation axis Ax.

In the illustrated example, the rotating member 50 includes a first member 51 supported by the other end portion support member 35 , and a second member 52 having a second shaft portion 50 a and being fixed to the first member 51 . The first member 51 has: a first portion 51a supported from the rear and lower side by the other end support member 35; The second portion 51b of the other end portion 40b of the hand member 40 . The first portion 51a has a hole through which the first shaft portion 35b is inserted. The second portion 51b supports the other end portion 40b of the handle member 40 from one side in the longitudinal direction of the second shaft portion 50a. Moreover, the 2nd member 52 has the 1st part 52a into which the 1st axial part 35b formed in the annular shape penetrates, and the 2nd part 52b in which the 2nd axial part 50a was formed. The second portion 52b supports the other end portion 40b of the handle member 40 from the other side in the longitudinal direction of the second shaft portion 50a. The second shaft portion 50 a extends from the second portion 52 b of the second member 52 to the second portion 51 b of the first member 51 . In addition, the 1st member 51 and the 2nd member 52 cannot fall off from the 1st shaft part 35b by the protrusion part 35c which protrudes from the 1st shaft part 35b.

As clearly shown in FIGS. 7 and 8 , the other end portion 40 b of the handle member 40 is provided with a shaft hole 40 c extending in a direction not parallel to the extending direction of the handle member 40 . The second shaft portion 50a of the rotating member 50 is inserted through the shaft hole 40c. Thereby, the handle member 40 can take the center line of the cylindrical second shaft portion 50a as the second rotation axis Bx in a state in which the one end portion 40a is detached from the one end portion support member 31, and the second rotational axis Bx 2. The rotation axis Bx is the center, and it rotates relatively with respect to the rotating member 50 (that is, with respect to the seat body 20). Furthermore, by allowing the rotation member 50 to rotate relative to the seat body 20 around the first rotation axis Ax as described above, the handle member 40 can be opposed to the seat body 20 around the first rotation axis Ax. rotate. That is, the handle member 40 is relatively rotatable with respect to the seat body 20 about the two rotation axes Ax and Bx which are not parallel to each other. Thereby, the posture of the handle member 40 with respect to the seat body 20 can be variously changed. In addition, even if the handle member 40 (the handle main body 41 ) is made of a material that is hard to elastically deform, such as non-foamed EVA (ethylene vinyl acetate copolymer), the one end portion 40 a of the handle member 40 can be easily removed from the The one-side end support member 31 is removed.

In the example shown in the figure, the first rotation axis Ax is orthogonal to the second rotation axis Bx. Thereby, the attitude|position of the handle member 40 with respect to the seat main body 20 can be changed efficiently. In addition, in a state where the one end portion 40a is connected to the one end portion support member 31, the other side end portion support portion is provided along the second rotation axis Bx. The outer edge 24a of the side wall portion 24 on the other side at the position of the piece 35. Accordingly, when the one-side end portion 40a of the handle member 40 is removed from the one-side end portion support member 31 and the handle member 40 is relatively rotated with respect to the seat body 20 about the second rotation axis Bx, it is possible to effectively A force for relative rotation is applied to the handle member 40 .

Here, an operation method of the handle member 40 of the child seat 10 of the present embodiment will be described. First, an operation method when the handle member 40 is moved from the position shown in FIG. 2 to the position shown in FIG. 11 through the position shown in FIGS. 9 and 10 will be described.
