Resin molded article

1. A resin molded article formed by injecting resin, the resin molded article comprising:

a main body; and

a joint section integrally formed on an outer wall surface of the main body, the joint section comprising a cylindrical section configured to insert therethrough a joint member for attaching the main body to a mating member,

wherein the joint section is formed to be asymmetric about a perpendicular plane which passes through a central axis of the cylindrical section and which is perpendicular to the outer wall surface of the main body,

wherein the cylindrical section is equidistant from two ends of the joint section;

wherein the joint section comprises:

a pair of left and right inclined wall sections integrally extending from both sides of the cylindrical section toward to outer wall surface of the main body; and

bored sections respectively formed between each of the inclined wall sections and the outer wall surface of the main body, and

wherein the pair of left and right inclined wall sections are asymmetric in thickness about the perpendicular plane,

wherein bottom wall sections are respectively formed at end portions of the bored sections to connect the respective inclined wall sections with the outer wall surface of the main body, and

wherein each of the bottom wall sections is asymmetric in thickness about the perpendicular plane.

2. The resin molded article according to claim 1 ,

wherein the pair of left and right inclined wall sections are equal lengths.

3. The resin molded article according to claim 1 ,

wherein the joint section forms an equilateral triangle around the cylindrical section.
