PURPOSE:To provide the ease with which a hollow wheel for walk-type rice- planting machines may be manufactured and mounted and to prevent the same machine from scraping up mud by embedding one end of each annular rigid member in the tyre bead part and fixing the other end to a frame member of the wheel. So as to define an airtight space inside the tyre between the rigid members. CONSTITUTION:One pair of annular members 22 and 23 are embedded, as shown by 22a and 23a, in a bead part 18 of a tyre body 7 and mounting parts 22b and 23b are tightened together by means of fixtures 5 and 6 and a bolt 28, with a sealing part 25 therebetween, thereby securing airtightness inside the tyre body 7. Such construction will provide the ease with the wheel may be manufactured and mounted, and reduce the extent to which mud is scraped up. |
