Recently, with the development of the industrial society, the opening of foreign markets has led to the increase in the number of large stores that sell large quantities of daily necessities, such as discount marts and large shopping centers. It is very popular with them. In addition, large stores such as the above are packaged in bundles of products so that consumers can purchase large quantities of necessities at a lower price than other distribution lines in line with the age of the nuclear family and the changes in lifestyles caused by the increase in women's social participation. Sell on display. These large stores are usually equipped with a cart, a shopping cart (shopping cart) in order to facilitate the buyer's convenience, so that consumers can conveniently purchase a large quantity.

In general, a conventional shopping cart is composed of a loading unit for receiving a large article, a frame supporting the loading unit, and a wheel mounted on the frame to easily move the shopping cart. Here, the wheels can be rotated 360 degrees and are usually provided with four.

However, such a conventional shopping cart can rotate the wheel 360 °, so if a large amount of goods are loaded in the loading section, the passage between the display rack and the display rack is narrow so that the cart can be rotated 180 ° in the opposite direction or cornered to the left and right. When the weights of objects are moved in the opposite direction to the rotating side, they often hit the shelves due to improper driving in the desired direction, or hit other people's carts. There was a problem that damage to the human body. In addition, since there is no separate brake device, it often happens that the user does not stop suddenly, but only hits a person in front of him or another cart.

Therefore, when cornering to the left and right sides of the store while shopping while pushing the shopping cart, the handle portion 13 by pulling the brake lever 21 of the cornering side of the two brake levers 21 installed on the handle portion 13. When rotated toward the side, the wheel 15 on the side to be cornered is braked by the braking unit so that the direction can be freely changed. When the shopping cart is to be stopped, the wheels 15 on both sides can be restrained by pulling the brake levers 21 on both sides.

However, the braking unit in the prior art is free to rotate the wheel frame in order to free the movement direction of the cart, thereby causing the braking wire connected to the cart body is gradually twisted, such that the cart is stopped, such as failure There was a frequently occurring problem.
