In addition, since the notch 26 can be easily molded, the number of processing steps does not increase.

また支持ケース１２内の前記ポンプユニット１３の重心位置Ｇよりも前記蓋部１１側の位置で前記支持ケース１２に前記切欠き部２６が設けられるので、切欠き部２６が設けられる部分で支持ケース１２を確実に割れさせることができ、支持ケース１２のうち最も脆弱である部分に前記切欠き部２６が設けられることによっても切欠き部２６が設けられる部分で支持ケース１２を確実に割れさせることができ、さらに前記切欠き部２６が、前記ポンプユニット１３を囲むようにして前記支持ケース１２の上ケース部材１８に設けられることによっても切欠き部２６が設けられる部分で支持ケース１２を確実に割れさせることができる。   Further, since the notch 26 is provided in the support case 12 at a position closer to the lid 11 than the center of gravity G of the pump unit 13 in the support case 12, the support case is provided at the portion where the notch 26 is provided. 12 can be reliably cracked, and the support case 12 can be reliably cracked at the portion where the cutout portion 26 is provided even when the cutout portion 26 is provided at the weakest portion of the support case 12. Furthermore, the notch 26 is provided on the upper case member 18 of the support case 12 so as to surround the pump unit 13, so that the support case 12 is reliably cracked at the portion where the notch 26 is provided. be able to.

本発明の第２の実施の形態について図３を参照しながら説明すると、支持ケース１２における上ケース部材１８には、所定値以上の荷重が作用するのに応じて該支持ケース１２を割れさせる切欠き部２７…が、支持ケース１２内の前記ポンプユニット１３の重心位置Ｇ（第１の実施の形態参照）より前記蓋部１１（第１の実施の形態参照）側の位置であって支持ケース１２のうち最も脆弱である部分に設けられるものであり、この第２の実施の形態では、前記支持ケース１２の上ケース部材１８に設けられる透孔２５に臨む前記切欠き部２７…が、上ケース部材１８の厚み方向に延びるようにして上ケース部材１８に設けられる。   The second embodiment of the present invention will be described with reference to FIG. 3. The upper case member 18 in the support case 12 is cut so as to break the support case 12 when a load of a predetermined value or more is applied. The notch 27 is a position closer to the lid 11 (refer to the first embodiment) than the center of gravity G (refer to the first embodiment) of the pump unit 13 in the support case 12. In the second embodiment, the cutout portions 27 facing the through holes 25 provided in the upper case member 18 of the support case 12 are The upper case member 18 is provided so as to extend in the thickness direction of the case member 18.
