Summary:PROBLEM TO BE SOLVED: To provide a heat insulation cover of a valve device capable of improving mountability to a valve housing, while expanding a heat insulation temperature range.SOLUTION: A heat insulation cover 10 is mounted on a cap of a valve housing of a ventilation valve, and comprises a peripheral wall 11 and a top wall 18 formed at one end of the peripheral wall 11. An opening end part 12 of the peripheral wall 11 comprises a folded part 13 having a shape of being folded to an inner peripheral side. At the opening end part 12 of the peripheral wall 11, formed is a notch groove 19 transecting an inner peripheral edge 14 of the folded part 13 in a circumferential direction.SELECTED DRAWING: Figure 1 【課題】保温範囲を広げつつも、弁ハウジングへの装着性を向上させることのできる弁装置の保温カバーを提供する。【解決手段】保温カバー１０は、通気弁装置の弁ハウジングのキャップに装着されるものであり、周壁１１と周壁１１の一端に形成された頂壁１８とを有する。周壁１１の開口端部１２は内周側に折り曲げられた形状の折り曲げ部１３を有している。周壁１１の開口端部１２には、折り曲げ部１３の内周縁１４を周方向に離断する切欠溝１９が形成されている。【選択図】図１
