ABSTRACT:
A direction changing device for a handle of a stroller comprises a main body, a pulling rod and a co-moving part; the handle is fixed to the main body, which is capable of pivoting on a fixing element of a support member of the stroller. The main body has a hollow, in which the co-moving part is movably received. The pulling rod has a hooked end engaging a slope of the co-moving part. The co-moving part has two concavities each communicating with a confining end of the hollow to form two locating holes for a locating pole of the support member to be passed thereinto. The locating pole engages either one of the concavities to prevent the main body from turning. When the pulling rod is pulled, the co-moving part will be moved further into the hollow for releasing the concavities from the engagement with the locating pole. Thus, the main body plus the handle can be pivoted to change direction of the handle.
