Attachment apparatus for two-wheeled vehicle parts for enabling highly reliable attachment

An attachment apparatus of parts for a two-wheeled vehicle, comprising:

• a first attachment part attached to component parts of a two-wheeled vehicle;
• a second attachment part provided to be attached to said first attachment part and fixed to the two-wheeled vehicle parts;
• a first fitting portion formed on one of said first and second attachment parts and having a single rail-shaped projection with at least one end open, wherein a recess is formed in a portion of said projection;
• and
• a second fitting portion formed in the other of said first and second attachment parts, and including a single groove having at least one end open and slidably fitting on said rail-shaped projection, and including a projected piece having a jutted portion formed on a tip end of said projected piece and movable in a direction of crossing over said groove, said jutted portion being engaged with said recess of said projection in said groove, wherein
• when said second attachment part is attached to said first attachment part by a fitting of said first and second fitting portions, said projected piece moves with said projection being fit into said groove, so that said recess and said jutted portion are engaged with each other, preventing a release of the fitting of said first and second fitting portions, and wherein a first projection is formed in a portion of said projected piece, and a second projection is formed in a position of said second attachment part corresponding to said first projection, with said recess and said jutted portion engaged with each other, so that said second fitting portion is prevented from falling off said second attachment part.
