ABSTRACT:
A front fork swivel control structure used in a jogging stroller is disclosed to use a button to control the position of a spring-supported locking shaft, for enabling the locking shaft to be selectively shifted between the locking position to lock the front fork to the front frame tube of the jogging stroller and to prohibit the front wheel from a swivel motion, and the unlocking position to unlock the front fork from the front frame tube for allowing a swivel motion of the front wheel. The button is operable with the foot when the user's hands are not free.
