<p><P>PROBLEM TO BE SOLVED: To obtain a bicycle capable of sufficiently ensuring the stability of handle operation even if a load applied on a front part is large. <P>SOLUTION: A parallel link mechanism portion 7 is mounted at a lower end portion of a steering shaft 3. The parallel link mechanism portion 7 has an upper part link 8, a lower part link 9, a first coupling link 10, and a second coupling link 11. A first front wheel 12 is rotatably mounted between coupling portions of the upper part link 8 and the lower part link 9 of the first coupling link 10. A second front wheel 13 is rotatably mounted between coupling portions of the upper link 8 and the lower link 9 of the second coupling link 11. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
