PROBLEM TO BE SOLVED: To provide a wheel structure of a baby carriage which uses a hollow wheel axle and can keep aesthetic appearance even when it is in any state of a back pushing state and a face-to-face pushing state.SOLUTION: A wheel structure of a baby carriage whose state can be changed between a back pushing state and a face-to-face pushing state includes: a hub member (22) which is swingably held by a carriage body frame (51); a hollow wheel axle (30) which penetrates the hub member (22); and wheels (6) which are rotatably held with respect to the hub member (22) with the hollow wheel axle (30) therein. Both ends of the hollow wheel axle (30) are respectively mounted with caps (33, 34) covering a center hole of the hollow wheel axle (30). In this case, typically a fixed flange (31) and a post-attached flange (32) are respectively installed at positions away from both end edges of the hollow wheel axle (30) toward the center side. |
