2. Description of the Related Art Infant tricycles are used for ages 1.5 to 3 years old. At about 2 years of age, they look in the direction they want to go, hold their steering wheel with their hands, turn their rudder, and use their feet. It is common to kick the ground and proceed. By doing so, you will acquire complex motor skills that allow vision, hand operation and foot movement to cooperate. Eventually, if the pedals can be lifted separately on the left and right, they will be able to strengthen their legs more than walking. However, when an infant is placed on a tricycle for the first time, the right and left feet do not reach the ground, depending on the age and the size of the body, and therefore, it is impossible to kick the ground with the feet as described above. Therefore, traveling (moving) of this tricycle for infants is accompanied by mothers (guardians)
It is common to push a tricycle.

In the operation of pushing the tricycle, the mother or the like stands beside the tricycle and puts a hand on one of the handles of the tricycle to guide the driver. In this case, the mother is lined up next to the tricycle. As the direction of travel is regulated, the mother standing beside the tricycle must bend down, forcing her to take a very cramped posture. For this reason, an infant tricycle equipped with a hand push bar behind the saddle has been developed to allow the accompanying mother and others to push the tricycle in an easy posture and to secure the safety protection of the infant riding the tricycle. Has been used.

[0004]

The push rod attached to the rear of the saddle is one in which a push rod separately formed is attached to a backrest disposed behind the saddle by retrofit, and the backrest is extended upward. Although there is a type provided with a push rod integrally therewith, any form is very convenient because an attendant can press the push rod while standing behind the tricycle and watch the infant from behind. However,
On a downhill, etc., the hand may be moved simply by putting its hand on it, and if this movement is to be stopped, the handwheel must be firmly grasped to prevent the tricycle from moving. However, it is very difficult for a mother or the like to perform the above operation.

[0005] The present invention has been made in view of the above-mentioned problems of the prior art.
It is an object of the present invention to provide an infant tricycle provided with a brake device that enables an attendant operating a push rod to stop the movement of the tricycle with a simple operation.
