Provided is a waste gate valve for opening/closing a bypass passage that bypasses an exhaust turbine of a turbocharger, wherein the waste gate valve comprises: a valve body (14) disposed in the bypass passage; an opening/closing lever (16) having an insertion hole (26) into which a valve shaft of the valve body is inserted, and being configured to open/close the bypass passage by moving the valve body; and a washer (18) having an insertion hole (28) which is positioned more toward the distal end side of the valve shaft than the insertion hole of the opening/closing lever and into which the valve shaft is inserted, the washer being fixed to the valve shaft. The washer has a bent part (32) that is bent along the outer shape of the lever. 种废气旁通阀，用于开闭将涡轮增压器的废气涡轮旁通的旁通通路，具有：阀芯(14)，其设于旁通通路；开闭杆(16)，其具有供阀芯的阀杆穿过的通孔(26)，通过使阀芯移动来开闭旁通通路；垫片(18)，其具有比开闭杆的通孔更靠阀杆的前端侧且穿过阀杆的通孔(28)，并且固定于阀杆；垫片具有沿着杆的外形弯曲的弯形部(32)。
