ABSTRACT:
A stroller includes a handle, a foldable mechanism securely connected with the handle, a pair of rear supports pivotally connected with the foldable mechanism and a pair of front supports pivotally connected with said foldable mechanism. The foldable mechanism has an upper controlling member having a pivotal switch received therein and a channel for receiving a coil spring therein and a lower controlling member having a stepped engagement surface provided thereon. A stepped engagement surface is formed on the switch such that the stepped engagement of the switch will match with the stepped engagement surface of the lower controlling member and provide a strong construction configuration when the stroller of the invention is in use and therefore is able to prevent accidental collapse when the stroller is receives a great impact.
