A tunnel path part of the movable boarding bridge configured as above is positioned to be separated from the rainwater receivers so that the rainwater receivers are not seen by passengers inside a tunnel. In addition, since there is no height difference caused by the rainwater receivers, there is an advantage in that problems such as passengers' sprained ankles can be resolved. ## Claims ### Claim 1 A rainwater receiver of a movable boarding bridge comprising: an outer tunnel; an inner tunnel disposed in the outer tunnel, an inner tunnel footpath provided in a form of a footpath that allows a passenger to pass, the inner tunnel footpath included in the inner tunnel; an outer tunnel footpath provided in a multilayer film, the outer tunnel footpath disposed below the inner tunnel footpath; and a rainwater receiver disposed below the outer tunnel footpath, wherein the outer tunnel footpath by which the passenger passes and the rainwater receiver are separated such that the rainwater receiver is not visible by the passenger walking the outer tunnel footpath. ### Claim 2 (depends on 1) The rainwater receiver of claim 1, wherein the inner tunnel comprises: the inner tunnel footpath; an inner side frame configured to support the inner tunnel footpath, the inner side frame being disposed below the inner tunnel footpath; and a footpath horizontal extension structure configured to allow the inner tunnel footpath and the inner side frame to be separate and to allow the inner tunnel footpath and the inner side frame to be arranged in the multilayer film. ### Claim 3 (depends on 2) The rainwater receiver of claim 2, wherein the footpath horizontal extension structure is provided in a shape of an open ended rectangle. ### Claim 4 (depends on 1) The rainwater receiver of claim 1, wherein a safety cover is provided in a gap formed between the outer tunnel and the inner tunnel. ### Claim 5 (depends on 4) The rainwater receiver of claim 4, wherein the safety cover is a brush. ### Claim 6 (depends on 4) The rainwater receiver of claim 4, wherein the safety cover is detachable. ### Claim 7 (depends on 1) The rainwater receiver of claim 1, further comprising: an outer side frame configured to form a level difference in the outer tunnel and change a fluid flow of rainwater. ### Claim 8 (depends on 7) The rainwater receiver of claim 7, wherein the outer side frame is provided in an L-shape. ### Claim 9 A rainwater receiver of a movable boarding bridge comprising: an outer tunnel; an inner tunnel disposed in the outer tunnel, wherein the inner tunnel includes: an inner tunnel footpath provided in a form of a footpath that allows a passenger to pass, the inner tunnel footpath included in the inner tunnel, an inner side frame configured to support the inner tunnel footpath, the inner side frame being disposed below the inner tunnel, footpath, and a footpath horizontal extension structure configured to allow the inner tunnel footpath and the inner side frame to be separate and to allow the inner tunnel footpath and the inner side frame to be arranged in a multilayer form; an outer tunnel footpath provided in a multilayer form, the outer tunnel footpath disposed below the inner tunnel footpath; and a rainwater receiver disposed below the outer tunnel footpath, wherein the outer tunnel footpath by which the passenger passes and the rainwater receiver are separated such that the rainwater receiver is invisible from the outer tunnel footpath. ### Claim 10 (depends on 9) The rainwater receiver of claim 9, wherein the footpath horizontal extension structure is provided in a shape of an open ended rectangle. ### Claim 11 (depends on 9) The rainwater receiver of claim 9, wherein a safety cover is provided in a gap formed between the outer tunnel and the inner tunnel. ### Claim 12 (depends on 11) The rainwater receiver of claim 11, wherein the safety cover is a brush. ### Claim 13 (depends on 11) The rainwater receiver of claim 11, wherein the safety cover is detachable. ### Claim 14 (depends on 9) The rainwater receiver of claim 9, further comprising: an outer side frame configured to form a level difference in the outer tunnel and change a fluid flow of rainwater. ### Claim 15 (depends on 14) The rainwater receiver of claim 14, wherein the outer side frame is provided in an L-shape. ### Claim 16 A rainwater receiver of a movable boarding bridge comprising: an outer tunnel; an inner tunnel disposed in the outer tunnel; an inner tunnel footpath provided in a form of a footpath that allows a passenger to pass, the inner tunnel footpath included in the inner tunnel; an outer tunnel footpath provided in a multilayer form, the outer tunnel footpath disposed below the inner tunnel footpath; a rainwater receiver disposed below the outer tunnel footpath; and a safety cover provided in a gap formed between the outer tunnel and the inner tunnel, wherein the safety cover is a brush and wherein the outer tunnel footpath by which the passenger passes and the rainwater receiver are separated such that the rainwater receiver is invisible from the outer tunnel footpath. ### Claim 17 (depends on 16) The rainwater receiver of claim 16, wherein the inner tunnel comprises: the inner tunnel footpath; an inner side frame configured to support the inner tunnel footpath, the inner side frame being disposed below the inner tunnel footpath; and a footpath horizontal extension structure configured to allow the inner tunnel footpath and the inner side frame to be separate and to allow the inner tunnel footpath and the inner side frame to be arranged in the multilayer form. ### Claim 18 (depends on 17) The rainwater receiver of claim 17, wherein the footpath horizontal extension structure is provided in a shape of an open ended rectangle. ### Claim 19 (depends on 16) The rainwater receiver of claim 16, further comprising: an outer side frame configured to form a level difference in the outer tunnel and change a fluid flow of rainwater. ### Claim 20 (depends on 19) The rainwater receiver of claim 19, wherein the outer side frame is provided in an L-shape.
