PROBLEM TO BE SOLVED: To provide a fuel cap with a breather mechanism capable of suppressing sound squeak from occurring when discharging fuel vapor, and also capable of suppressing an increase in cost and the enlargement thereof.SOLUTION: A fuel cap with a breather mechanism is a cap that openably closes an oil supply port of a fuel tank T, and comprises a breather passage 20 that communicates the inside of the fuel tank T with the atmosphere A, and a valve 30 provided at the breather passage 20. The valve 30 includes a bearing surface 27 and a valve port 28 provided in the breather passage 20, a valve body 31 that closes/opens the valve port 28 by coming into contact with, and separating from the bearing surface 27, and a spring 32 for bringing the valve body 31 into contact with the bearing surface 27 until the inner pressure of the fuel tank T becomes or exceeds a predetermined pressure. The valve 30 includes a separation control device 40 that makes the valve body 31 incline and separate against and from the bearing surface 27 when the valve body 31 separates from the bearing surface 27.SELECTED DRAWING: Figure 1

    【課題】燃料蒸気排出時の音鳴きを抑制できるとともに、コストアップや大型化を抑制できるブリーザ機構付き燃料キャップを提供する。【解決手段】燃料タンクTの給油口を開閉自在に塞ぐキャップであり、燃料タンクTの内部と大気Aとを連通するブリーザ通路20と、ブリーザ通路20に設けられたバルブ30とを備え、バルブ30が、ブリーザ通路20内に設けられた座面27および弁口28と、座面27に離当接することで弁口28を開閉する弁体31と、弁体31を、燃料タンクTの内圧が所定の圧力以上となるまで座面27に当接させるばね32とを有し、バルブ30は、弁体31が座面27から離間する際に、弁体31を座面27に対して傾けて離間させる離間制御装置40を備えている。【選択図】図1
