Abstract
A locking device for a stroller includes a stem member disposed on a front wheel frame of the stroller. The stem member has a reduced intermediate portion with a radial locking hole. A coupling member is disposed to interconnect right and left ends of a connecting frame of the stroller, and is sleeved on and is turnable relative to the stem member. A lateral mount member has one end disposed on the coupling member, and a through hole communicated with the stem member and aligned with the locking hole when the coupling member is turned relative to the stem member to a lockable position. A locking member has a spindle portion disposed in the through hole, and includes an actuated end and a latch portion extendable into and retractable from the locking hole.
