A hollow portion 30 a having a substantially square or substantially rectangular shape is formed at the center of the movable portion 30. In the movable portion 30, four identically shaped rails 31 that are curved as viewed from the X direction in FIG. 2 are formed at the positions of the four corners corresponding to the rollers 21 of the holding portion 20. Specifically, as shown in FIG. 6, each rail 31 is formed so as to extend inward from the side edge of the movable portion 30. The movable part 30 is placed on the holding part 20 so that the rails 31 at the four corners of the movable part 30 are in contact with the rollers 21 at the four corners of the holding part 20, respectively. At this time, the movable part 30 is substantially parallel to the holding part 20.

Further, as shown in FIG. 9, the upper edge 21a and the lower edge 21b of the cross section of the roller 21 in the direction orthogonal to the reciprocating direction of the movable portion 30 (the Y direction in FIG. 2) are convexly protruding outward.

Further, a gap g is provided between the roller 21 and the pair of plate-like members 22 a and 22 a of the support member 22 located on both sides of the roller 21. Here, the bending radius R _B in the cross section of the rail 31 shown in FIG. 9 is larger than the bending radius R _A of the upper edge 21 a and the lower edge 21 b of the cross section of the roller 21. As a result, the roller 21 and the rail 31 come into contact with each other at a single point P in the cross-sectional view shown in FIG. 9, and the frictional force acting between the roller 21 and the rail 31 can be reduced. And when the movable part 30 moves with respect to the holding | maintenance part 20 in the axial direction (left-right direction in FIG. 9) of the axis | shaft 21c of the roller 21, a rail load is applied to the movable part 30 from the child-care instrument main body part 11. A downward force acts on 31, the roller 21 rotates, and the movable portion 30 moves so that the roller 21 contacts the central valley portion of the rail 31. Thus, the position of the roller 21 can always be maintained at the central valley portion of the rail 31 in the cross section in the direction orthogonal to the reciprocating direction of the movable portion 30 (Y direction in FIG. 2) (see FIG. 9). ).

  As shown in FIG. 5, the movable portion 30 is provided with a roller stop portion 33 made of a buffer member such as rubber below the end portion 31 a in the longitudinal direction of the rail 31. Specifically, as shown in FIG. 5, in the two rails 31, 31 arranged side by side in the reciprocating direction of the movable portion 30 (the left-right direction in FIG. 5), the roller stop provided on one rail 31 is stopped. The roller stop portion 33 provided on the portion 33 and the other rail 31 is disposed closer to the center portion of the movable portion 30 among the corresponding rails 31 and 31. When the movable unit 30 moves in the left-right direction in FIG. 5 with respect to the holding unit 20 and the roller 21 approaches the vicinity of the end 31a of the rail 31, the roller stopping unit 33 contacts the roller 21 and holds the holding unit. The position of the movable part 30 with respect to 20 is regulated. Moreover, since the roller stop part 33 consists of buffer members, such as rubber | gum, the impact when the roller stop part 33 collides with the roller 21 can be relieved. In addition, although the example which provided the roller stop part 33 which consists of a buffer member in the end of the rail 31 was shown, you may install the roller stop part 33 not only in the end of the rail 31, but in both ends, respectively.

  Further, in the hollow portion 30a at the center of the movable portion 30, two engaged members 32 made of a rod-like body extending in the X direction in FIG. Both ends of each engaged member 32 are respectively attached to the inner side surface of the hollow portion 30a at the center of the movable portion 30, and each engaged member 32 is in relation to the central vertical surface of the movable portion 30 in the X-axis direction. They are arranged symmetrically.

  As shown in FIGS. 2, 3, 10, and 11, the lock unit 40 that fixes the movable unit 30 to the holding unit 20 is placed on the holding unit 20, and the engaged member of the movable unit 30.

The angle A formed by the connected straight line with respect to the horizontal plane is slightly larger than 90 degrees, for example, 100 degrees. In this state, the movement of the horizontal movement member 47 is restricted by the holding portion 20 so that the horizontal movement member 47 does not slide further to the heel side (left side in FIG. 10).

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

  First, the operation in which the movable part 30 attached to the seat part 11a side of the child-care instrument main body part 11 reciprocates on the holding part 20 attached to the leg part 13 side will be described below. In a state where the movable part 30 is stopped with respect to the holding part 20, as shown in FIG. 7, a downward force is applied to the rail 31 by the load applied to the movable part 30 from the side of the child-care instrument main body 11 side. Since the movable portion 30 is lowered as a whole, the roller 21 of the holding portion 20 comes into contact with the central valley portion of the curved rail 31.

  At this time, for example, when the operator moves the child-care instrument main body 11 including the seat part 11a and the back part 11b of the child-care instrument 10 in the front-rear direction, the movable part 30 moves in the Y direction of FIG. Then, the roller 21 rotates and the rail 31 moves on the roller 21, and the end portion 31a of the rail 31 comes close to the roller 21 as shown in FIG. At this time, the movable part 30 is slightly lifted with respect to the holding part 20.

  In the state shown in FIG. 8, when the child-care instrument main body 11 including the seat 11 a and the back 11 b of the child-care instrument 10 is released, a downward force is applied to the rail 31 by the load applied to the movable part 30 from the child-care instrument main body 11. The roller 21 rotates and the rail 31 moves on the roller 21. At this time, the movable part 30 descends with respect to the holding part 20 due to the load from the child-care instrument main body part 11, and then the movable part 30 rises again due to the inertia of the movable part 30 with respect to the holding part 20. The movable part 30 reciprocates on the holding part 20 in a substantially horizontal direction while such a movable part 30 repeatedly descends and rises with respect to the holding part 20.

  Next, the operation of fixing the position of the movable unit 30 with respect to the holding unit 20 will be described below. When the position of the movable portion 30 is not fixed and the movable portion 30 is reciprocally movable with respect to the holding portion 20, as shown in FIG. It is in a state of being located below the engaged member 32 of the movable portion 30.

  In the state shown in FIG. 10, when the operator presses the operation lever 42 in the heel direction (left direction in FIG. 10), the horizontal movement member 47 of the link mechanism 45 slides on the holding unit 20 in the left direction in FIG. To do. Here, the connecting member 48 of the link mechanism 45 has one end 48a connected to the horizontal moving member 47 so as to be movable in the horizontal direction, and the other end 48b connected to the engaging member 41 so as to engage with the engaging member guide. It is movable in the vertical direction along the groove 26a of the rail 26. For this reason, when the horizontal direction moving member 47 slides on the holding portion 20 in the left direction, one end 48a of the connecting member 48 rotatably attached to the horizontal direction moving member 47 moves in the left direction. At this time, since the other end 48b is connected to the engaging member 41, it cannot move in the left-right direction, and the connecting member 48 tilts so that the other end 48b rises with respect to the holding portion 20 as shown in FIG. As a result, the other end 48b of the connecting member 48 moves upward. As a result, the engaging member 41 rotatably attached to the other end 48b of the connecting member 48 is lifted vertically upward along the groove 26a of the engaging member guide rail 26, as shown in FIG. The combined member 41 engages with the engaged member 32, and the engaging member 41 lifts the engaged member 32 in this way. At this time, the rail 31 of the movable part 30 is separated from the roller 21 of the holding part 20, and the position of the movable part 30 is fixed by the engaging member 41 and the engaged member 32.

  Here, before and after the engaging member 41 of the lock portion 40 lifts the engaged member 32 of the movable portion 30, the one end 48 a of the connecting member 48 that is rotatably attached to the horizontal moving member 47 is moved horizontally. As the member 47 slides on the holding portion 20, a position on the nearer side than the other end 48b in the pressing direction of the operation lever 42 (see FIG. 10) and a position slightly further on the rear side than the other end 48b (see FIG. 11). ) To move between. If the engagement member 41 of the lock portion 40 lifts the engaged member 32 of the movable portion 30, one end 48 a of the connecting member 48 is closer to the front side than the other end 48 b in the pressing direction of the operation lever 42 ( Consider a case in which it can only move to the right side of FIG. In this case, when the engagement member 41 lifts the engaged member 32 and releases the operation lever 42, the load is applied to the movable portion 30 so that the other end 48 b of the connecting member 48 is lowered. A force to be pushed down is applied, and one end 48a of the connecting member 48 is positioned on the near side (right side in FIG. 11) than the other end 48b, so that it is pushed toward the near side (right direction in FIG. 11) with respect to the one end 48a. A force is applied, and the horizontal movement member 47 is forced to slide forward (to the right in FIG. 11) to return to the state before the engagement member 41 is engaged with the engaged member 32. Is also possible.

  However, in the present embodiment, in the state after the engaging member 41 is engaged with the engaged member 32 and lifted, the one end 48a of the connecting member 48 is pressed by the operating lever 42 as shown in FIG. Since it is positioned slightly on the heel side (left side in FIG. 11) in the direction, the hand is released from the operation lever 42 after the engaging member 41 lifts the engaged member 32. However, the loaded load applied to the movable portion 30 is a force that pushes the one end 48a in the saddle direction (leftward in FIG. 11), and the horizontal movement member 47 is forced forward (rightward in FIG. 11). The state after the engaging member 41 lifts the engaged member 32 can be maintained without sliding.

  According to the present invention, as described above, the movable portion 30 is placed on the holding portion 20 so as to be reciprocally movable in a substantially horizontal direction, and is provided below the child-care instrument main body portion 11 and engaged with the bottom portion.
