A caster-locking device for baby carriages (1) has a fixed shaft (7) secured to the lower end of a front leg (2) of the baby carriage, a notched cylindrical locking body (8) attached to the fixed shaft, a caster bracket (10) installed for rotation on the fixed shaft, a ground-engaging wheel (4) rotatably mounted on an axle (13) inserted in the caster bracket, a locking lever (14) rotatably attached to the caster bracket and having an operating knob (14d) adapted to be operated for rotation from the outside. Holders (15, 16, 17, 18, 19) hold the locking lever engaged with or disengaged from one or more notches (8a or 8b) in the locking body. The orientation of the locking lever and notches relative to each other and to the wheel is such that the locking can take place only when the wheel is in a predetermined position. |
