Abstract
The invention provides a transition board apparatus for a passenger bridge and a spring leaf thereof. A transition board apparatus includes a transition board and a spring leaf, wherein the transition board comprises a hinged end, a free end and the transition portion between them. The hinged end hinges on the end of the first tunnel bottom plate. The spring leaf is provided with the holding portion, which is secured on the sidewall of the first tunnel, and the bearing portion, which is used to raise the transition board up. Thus, there is a clearance between the free end and the bottom plate ornament laid on the second tunnel bottom plate. Therefore, when the second tunnel is moving back and forth relative to the first tunnel, the friction between the transition board and the bottom ornament can be avoided in order to protect the bottom plate ornament.
