<P>PROBLEM TO BE SOLVED: To generate a sound for informing the approach of a vehicle to pedestrians around when the vehicle superior in silence travels at a low speed. <P>SOLUTION: This wheel 11 of a vehicle wheel 10 has a rim part 13 in which a tire 12 is fitted, and a disc part 14 for supporting the rim part 13. The disc part 14 has a hub mounting part 15, and a column 16 radially arranged from the center of the wheel 11. A cylindrical hole 21 is arranged toward the center of the wheel 11 from the rim part 13 having a sounding part 22 inside the column 16. A sealing plug 23 is arranged in an opening part of the cylindrical hole 21, and a cylindrical space 20 is constituted. The wheel is constituted so that, when the vehicle wheel 10 rotates, the sounding member 22 reciprocates in the longitudinal direction in the cylindrical space 20, and generates a collision sound by colliding with a bottom part 24 or the sealing plug 23 of the cylindrical hole 21. <P>COPYRIGHT: (C)2012,JPO&INPIT |
