A baby carriage comprises a pair of push rods, a push rod connecting member for connecting upper end portions of the pair of push rods with each other, a pair of push rod locking members for fixing positions of the push rods, a pair of opened state locking members for fixing/maintaining the baby carriage in an opened state, a pair of engagement release members provided to be displaceable between lowermost, intermediate and uppermost positions along the push rods, a wire for connecting the pair of engagement release members with each other and an operating member connected to the wire at the central portion of the push rod connecting member. When the operating member is manually brought into a second position, the engagement release members are pulled up by the wire toward the intermediate positions, to push up the opened state locking members. Consequently, the baby carriage is released from the locked opened state. When the operating member is manually brought into the third position, the engagement release members are pulled up by the wire toward the uppermost positions, to push up the push rod locking members. Consequently, the push rods are unlocked.
