      SOLUTION: The frame is provided with two bases 12, 13 of which rear part horizontally extends rearward to form a space for receiving a rear wheel, and two stays 14, 15 obliquely extending toward each one end part of the bases 12, 13 and joined with the same at acute angles by a joining means. A pair of recess parts for receiving a shaft of the wheel are arranged at positions where the stays 14, 15 cross the bases 12, 13. Each recess part of the pair of the recess parts is provided with a first notch 23 including a semicircular bottom on one flat section of the base and a second notch 24 including a semicircular bottom on an end part flat section of the stay and arranged to face the first notch 23.
