Abstract
A connecting structure for a baby carriage disposed between a pair of push rods (1) and a push rod-connecting member (7) has a pair of brackets (16) extending inwardly from the push rods (1), a pair of turning shafts (17) provided on the brackets (16), a pair of sockets (18) supported by the turning shafts (17) for a folding movement of the sockets relative to the brackets (16). Each socket (18) receives one end of the push rod-connecting member (7) so that the member (7) can be rotated, around its longitudinal axis. A pair of engaging sections (19) is fixed on the push rods (1) at positions opposed to the lateral surfaces of the ends of the push rod-connecting member (7). A pair of lock control sections (20) is secured to the ends of the push rod-connecting member (7) for cooperation with the respective engaging section. For this purpose each locking section has an abutting portion (22) of relatively large radius and a clearing portion (23) of relatively small radius. By rotating the push rod-connecting member (7) around its longitudinal axis, the locked and unlocked states can be selceted, whereby in the locked state the abutting portion (22) is locked against the respective enga…
