[0014]

As described above, according to the shopping trolley according to the present invention, the storage case has a shape in which the lower part of the front surface is cut out, so that the storage case can be seated on the seat surface forming member. When an elderly man tries to move his feet backward, the range of his feet hitting the front of the storage case can be increased. Therefore, when an elderly person sitting on the seating surface forming member tries to stand up, the feet can be sufficiently moved backward, and as a result, when the upper body leans forward to shift the center of gravity of the upper body forward. Since the foot can be positioned immediately below the position of the center of gravity of the whole body or in the vicinity thereof, the user can stand up easily.

Also, when an elderly man standing in front of a shopping trolley attempts to sit on the seating surface forming member, the foot can be similarly sufficiently moved backward, so that the middle of the seating operation can be achieved. It can also prevent the elderly from giving anxiety.
Further, as described above, even if the storage case is cut out at the lower part of the front surface, it is sufficient that the notch is formed only in a limited portion, so that the volume of the storage case cannot be substantially reduced. Absent.

The appearance of the storage case is given a light feeling, and the effect of enhancing the beauty of the shopping wheelbarrow can be expected. Further, when the storage case is cut off at the lower front portion thereof, luggage such as shopping in the storage case can be naturally moved rearward along the cut front lower portion.

More specifically, the seat surface forming member also serving as a lid of the storage case is often attached to the storage case so as to rotate around the rear end thereof.
When the seat surface forming member is opened, a large opening is formed on the front side of the storage case, so that the load is usually inserted into the storage case from the front side. For this reason, the luggage is often placed on the front of the storage case without any effort and is placed casually. However, if the luggage is placed in the front of the storage case in this way, the center of gravity of the shopping trolley moves to the front wheel side, and this center of gravity is
The person who stands behind the rear wheel and pushes the shopping wheelbarrow is far away. As a result, the operation of pushing the shopping wheelbarrow, particularly the turning operation, becomes difficult.

Under such a background, according to the present invention,
Since the storage case is notched at the lower front part, the luggage in the storage case moves rearward along this cut-out lower part of the front even if the storage case is placed at the front of the storage case. It moves naturally and can prevent the luggage from being shifted in the storage case. Therefore, it is possible to prevent the operability of the shopping trolley from being hindered by the bias of the center of gravity toward the front wheel.

As described above, the luggage in the storage case moves rearward along the notched front lower portion due to vibrations received while the shopping trolley is being moved. Can be further encouraged. Further, in the present invention, the storage case is cut out at the lower front part thereof. When the inner surface of the storage case forms an inclined surface at the lower part of the cut front part, the storage case as described above is formed. The action of moving the luggage, which is placed on the front part, to the rear can be more reliably and smoothly achieved.

Further, in shopping for pushcart according to the present invention, the body frame is provided with a reinforcing bar connecting two front legs attaching the left and right front wheels to each lower end, and between the two front legs, the reinforcing rods Since it is arranged along the notched front lower part of the storage case, it is possible to prevent such a reinforcing rod from limiting the range in which the foot can be moved backward while reinforcing the main body frame. .
