PROBLEM TO BE SOLVED: To provide a structure of a rim made of a light alloy which does not spoil a good look of the external appearance by the lightening when the weight of the external surface of the rim made of the light alloy being often used for a motorcycle is reduced by lightening, and also, has less manhours for the lightening, and which facilitates the cleaning of mud which is easy to adhere at the time of use. SOLUTION: A bead sheet section is arranged on both sides by pinching a rim base section which is combined with spokes, and a side ring which rises circumferentially from the outside of the bead sheet section is provided, and then, they are integrally molded of the light alloy. In this rim, a base section which is formed with a thickness being approximately equal from the bead sheet section to the side ring, and a swelling section which swells into an arc shape to the outside on the external surface of the side ring central section of the base section are provided. Then, the skirt section of the swelling section is smoothly connected with the base section. COPYRIGHT: (C)2007,JPO&INPIT
