  It may be desired to conceal the brake pipe assembly as much as possible from the viewpoint of appearance. However, in order to reduce the exposure of the brake piping assembly to the outside, when arranging a plurality of rows of brake piping assemblies in a row, it may not be possible to secure an arrangement space.

  FIG. 24 is a perspective view showing a layout of brake piping and a main harness in a conventional motorcycle. FIG. 25 shows the periphery of the boundary between the fuel tank and the seat in the motorcycle. The left side of FIG. 24 is the front side of the motorcycle, and the right side of FIG. 24 is the rear side of the motorcycle. The main pipe 352 is a part of the frame of the motorcycle. Three brake pipes 311, 325, and 327 and a main harness 315 are arranged along the main pipe 352. Each brake pipe 311, 325, 327 constitutes a part of the brake pipe assembly. The three brake pipes 311, 325, 327 are arranged in a line. Note that “arranged in a line” means that the three brake pipes 311, 325, and 327 are positioned on a straight line in the cross section.

However, the arrangement space required for the three brake pipes 311, 325, and 327 arranged in a row is larger than the empty space. Here, the state where the arrangement space is larger than the empty space means that the maximum dimension of the arrangement space is larger than the maximum dimension of the empty space on the cross section of the main pipe 352. That is, in terms of volume, even if the arrangement space is larger than the empty space, the arrangement space does not fit in the empty space. For this reason, the entire three brake pipes 311, 325, and 327 and the main harness 315 cannot be disposed in the empty space. Therefore, only the main harness 315 is arranged in the empty space. The three brake pipes 311, 325, and 327 are arranged on the side of the main pipe 352 because they cannot be arranged in the empty space. As a result, as shown in FIG. 25, the three brake pipes 311, 325, 327 are exposed.
