A seat rail of a motorcycle has two side members configured using fiber-reinforced resin. Each side member has a main body and an upper flange portion that protrudes in a width direction of a vehicle body from an upper side edge of the main body. An attachment element for attachment to the main frame of the vehicle body is provided at a front end portion of each side member, and the seat rail has at least one upper connecting member that connects two upper flange portions. The upper flange portion has an inflection section connecting the front section and the rear section such that the rear section of the upper flange portion is raised toward an upper direction with respect to the front section, and the inflection section is arranged between the front end portion of the side member and a foremost upper connecting member.

Seat rail of motorcycle

Disclosed herein is a straddle type vehicle that uses resin seat rails, and in which attachment parts of footrests for an occupant of a rear seat of a tandem seat are provided to fastening parts of a member connecting right and left seat rails. The straddle type vehicle may include: resin right and left seat rails extending in a vehicle longitudinal direction; a middle connection member connecting the seat rails to each other; a tandem seat assembled to the seat rails and footrests for an occupant of the tandem seat respectively coupled to the right and left seat rails. A connection part of the middle connection member of the seat rails is provided within a range obtained by vertically extending an outer edge of an attachment part of the footrest coupled to each of the seat rails in side view.

Straddle type vehicle

According to the present invention, even if an analysis target has a complicated shape, for example, two or more cutting surfaces, elements can be automatically extracted therefrom without reducing any analysis accuracy. For each voxel interfering with shape data, an interference polygon is created inside the shape data using interference surfaces between the shape data and the interior of the voxel. After the interference polygon is created, a divided polygon is created by moving one of the vertexes of the interference polygon, which has a predetermined property, to another vertex. The divided polygon includes the vertex that has not been moved and vertexes of the voxel inside the shape data. An element of a predetermined shape is extracted on the basis of the relationship between a plurality of vertexes of the divided polygon.

The invention involves: a voxel data reading process (step S ) used to read voxel data on the shape of an object of analysis that is defined by the groups of rectangles of voxels; a boundary determination process used to determine whether each voxel contained in the voxel data, which is read in the voxel data reading process S belongs to a boundary separating the inside from the outside of the shape of the above-mentioned object of analysis; a connected voxel determination process (step S ) used to recursively determine whether the voxel at each level is connected to the other voxel that is determined to belong to the boundary in the boundary determination process; and a voxel redefinition process used to redefine each voxel, at each level in the groups determined in the above-mentioned connected voxel determination process S to the voxel at each level several times wider than the rectangle of a voxel determined to belong to the boundary in the above-mentioned boundary determination process.
