<p>PROBLEM TO BE SOLVED: To provide a buffer wheel assembly body capable of preventing an external shock from being transmitted to a fragile article in a baggage bag. SOLUTION: The buffer wheel assembly is provided with a wheel assembly body 22a, a support member 42, a spring member 46, and a wheel member 44. A wheel housing 40 is attached to the lower end of the bag 20. The support member is fitted in the housing to be movable between first and second positions. The spring member is disposed between the wheel housing and the support member to correspond to the movement of the support member from the first position to the second position. When the bag is tilted and pulled, the wheel member is rotated while engaging with a plane and the bag can be transferred along the plane. When the bag is tilted and pulled and the support member moves between the first and second positions, the support member is substantially vertically set in order. The first and second wheel members can be fitted to the bag to improve the safety.</p> |
