DEPOSIT ELIMINATOR FOR TIRE

PROBLEM TO BE SOLVED: To prevent a deposit on the running surface of a tire from coming into the interior of the tire to release a gas from a pressure gas sealing section to the outside. SOLUTION: A deposit eliminator 40 for tires has a contact member 45 which can be brought into contact with or separated from the tire surface to eliminate foreign matter deposited to the running surface of the tire 20 during the revolution of the tire 20 on run. The contact member 45 can be shifted alternately to a first position and to a second position. At the first position, the contact member 45 is separated apart from the tire surface by a gap distance Ga and can mechanically be kept at a locked position, and at the second position, the contact member 45 allows execution of one or both of operations of bringing the contact member 45 into contact with the tire surface by a press force F to mechanically keep the contact member 45 at a locked position and manually pressing the contact member 45. The tire attachment eliminator 40 is fitted to a bicycle, and is capable of operating in interlocking with braking operation. COPYRIGHT: (C)2008,JPO&INPIT
