It is difficult to press-fit the cushion 82 having the structure disclosed in Japanese Utility Model Laid-Open No. 6-23835.

In order to remedy the above disadvantages, in Japanese Patent Laid-Open No. 2014-223838, as shown in FIGS. 13 to 15, a cushion 92 arranged in a conventional roof carrier protector 90 is divided into a plurality of

blocks

92a and 92b. Thus, a technique is disclosed that enables mounting to a crossbar 110 having a shape that is wider in width than in length.

Although the shape of the mountable crossbar increases by using the structure of JP-A-2014-223838, depending on the shape of the crossbar, such as a small crossbar having a wide width with respect to the vertical width, Floating does not follow well, the contact area of the protector 90 with respect to the crossbar is reduced, and the protector 90 moves relative to the crossbar when shaking during running or acceleration in the longitudinal direction of the crossbar occurs. There was a bug.

In addition, the

cushions

82 and 92 used in the conventional technology are manufactured by cutting a cushion formed into a substantially cylindrical shape by extrusion using an exclusive-shaped die into an appropriate length. Since the same shape as that at the time of use was maintained during storage and sales, the volume was increased, and the efficiency during transportation, storage and display was poor.
