Thus, it is possible to form an entrance / exit for the seat portion by moving to the retreat position.
[0007]
For this reason, when the movable upright member described above is moved to the retracted position to form the entrance / exit, it is possible to easily carry the child on and off the seat portion.
In this case, “loading onto the seat” means that when the child is lifted, the toe of the child is substantially the same level as the seating surface level of the seat (the child is lifted to such a height. In this case, it is said that the child is placed on the seat by moving the child as it is or lowered from the seat.
[0008]
The “retracting position that does not disturb the“ loading on and off the seat ”” refers to a position that does not hit the child when the child is lifted and moved laterally as described above.
Therefore, the retracted position is set from an operational viewpoint, and the positioning and the moving direction for the retracting change depending on what the standing member is specifically.
In other words, the movable upright member described above is not unique, and it is never limited that the member (standing member) existing at a position higher than the seating surface level after the retreating movement is lost. is not.
[0009]
As described above, the seat portion may have a bucket shape, and in this case, a backrest is provided at the rear portion of the seating surface, and side guards are provided on both the left and right sides of the seating surface.
Therefore, the movable upright member described above can be one or both of the side guards.
In such a case, the child may be taken off from the side of the parked bicycle.
[0010]
If both side guards are movable, the child can be placed on and off from either the left or right side of the bicycle.
The side guard has a front side position on the lower side thereof that is pivotably supported around a support shaft that protrudes from a front side surface position of the seating surface and is movable back and forth. An engagement piece that can be engaged and disengaged between the rear end position and a catch portion provided on the backrest can be provided.
The movable upright member described above can be a backrest or a handle provided in front of the seat portion (not a bicycle handle but a handle provided in an auxiliary seat device).
