ABSTRACT:
A baby carriage backrest inclination angle adjusting mechanism comprises a backrest support member, a friction member turnable between a first and a second position, turning operating means for operating the friction member for turning movement, and a prop member for supporting the backrest support member from behind. The backrest support member is formed with a projecting wall and an elongated opening extending parallel to the projecting wall. A pin which interconnects the backrest support member and friction member extends through the elongated opening and is movable along the elongated opening. The friction member has a long radius portion located at a relatively long distance from the pin and a short radius portion located at a relatively short distance from the pin. When the friction member is in the first position, the long radius portion abuts against the projecting wall. On the other hand, when the friction member is in the second position, the short radius portion is opposed to the projecting wall with some clearance defined therebetween.
