ABSTRACT:
In both the opened and closed states of a baby carriage, the push rod-side engaging portion (35) of a lock operating member (29) engages either of the two engaging portions (20, 21) formed on a connecting rod (4), whereby each of the opened and closed states can be locked. For example, in the opened state, the push rod-side engaging portion (35) engages the opened state locking purpose connecting rod-side engaging portion (20) of the connecting rod (4), whereby the push rod (3) and connecting rod (4), which are now in their linear state, are maintained in this state, and since this engagement is forced by a spring (34), a reliable locked state can be obtained. Further, in the closed state, the push rod-side engaging portion (35) engages the closed state locking purpose connecting rod-side engaging portion (21) of the connecting rod (4), whereby the push rod (3) and connecting rod (4), which are now in their bent state, are maintained in this state, with the spring (34) ensuring that the locked state is reliable. When it is desired to cancel these locked states, this can be attained by sliding the lock operating member (29) upward.
