A baby carriage has front legs, rear legs disposed to cross the front legs, push rods pivotally connected at the lower ends thereof to the upper ends of the front legs, cross rods crossing each other in the form of the letter X and pivotally connected at the upper ends thereof to the push rods and at the lower ends to the rear legs, lateral frame members pivotally connected at the front ends thereof to the upper ends of the rear legs and at the rear ends thereof to the push rods, widthwise connecting members bendably constructed and defining the width of the baby carriage when the latter is in the opened state, push rod locking mechanisms for inhibiting the push rods from pivoting relative to the front legs when the baby carriage is brought into the opened state, and cross-rod locking mechanism adapted to abut against the upper ends of the cross-rod to inhibit an upward movement of the cross-rods when the baby carriage is brought into the opened state.
