　このような形状のケーシング用部品４１００を、型を使用した成型によって製造する場合に、ケーシング用部品４１００の内部の空洞部は、型を引き抜くことができないアンダーカット部と呼ばれる部分である。したがって、このような形状のケーシング用部品４１００を、型を使用した成型によって簡単に製造することはできなかった。すなわち、他の部品と係合するようにケーシング用部品の開口部の周囲の少なくとも一部に、ケーシング用部品の内側に突出した部分を備えたケーシング用部品であって、型を使用した成型によって簡単に製造することのできるケーシング用成型部品は開発されていなかった。　 When the casing component 4100 having such a shape is manufactured by molding using a mold, the hollow portion inside the casing component 4100 is a portion called an undercut portion where the mold cannot be pulled out. Therefore, the casing part 4100 having such a shape cannot be easily manufactured by molding using a mold. That is, a casing component having a portion protruding inside the casing component at least part of the periphery of the opening of the casing component so as to be engaged with another component, and by molding using a mold A molded part for the casing that can be easily manufactured has not been developed. *

　本発明の第１の態様による筒状のケーシング用成型部品は、筒の少なくとも一方の端部の周縁部に、該筒の軸方向に伸びる複数の突起部を備えており、該複数の突起部が該筒の内側に折り曲げられた状態で、他の部品を該筒の内側に嵌め合せるように構成されている。 The cylindrical molded part for casing according to the first aspect of the present invention includes a plurality of protrusions extending in the axial direction of the cylinder at the peripheral edge of at least one end of the cylinder, and the plurality of protrusions. Is configured to be fitted to the inside of the cylinder in a state of being folded inside the cylinder.
　本態様による筒状のケーシング用成型部品は、筒の少なくとも一方の端部の周縁部に、該筒の軸方向に伸びる複数の突起部を備えている。本発明による筒状のケーシング用成型部品は、成型される際には、アンダーカット部を有しないので、型を使用した成型によって簡単に製造することができる。 The cylindrical molded part for casing according to this aspect includes a plurality of protrusions extending in the axial direction of the cylinder at the peripheral edge of at least one end of the cylinder. Since the cylindrical molded part for a casing according to the present invention does not have an undercut portion when being molded, it can be easily manufactured by molding using a mold.
　本発明の一実施形態によるケーシング用成型部品は、前記複数の突起部の折り曲げられる部分の肉厚が、他の部分の肉厚よりも薄くなるように構成されている。 The molded part for casing according to an embodiment of the present invention is configured such that the thickness of the bent portion of the plurality of protrusions is thinner than the thickness of the other portion.
　本実施形態によれば、前記複数の突起部の折り曲げられる部分の肉厚が、他の部分の肉厚よりも薄くなるように構成されているので、前記複数の突起部を前記筒の内側に容易に折り曲げることができる。 According to the present embodiment, since the thickness of the bent portion of the plurality of protrusions is configured to be thinner than the thickness of the other portions, the plurality of protrusions are arranged inside the cylinder.

The diameter of the circle inscribed in the bent protrusion 1303 decreases according to the distance from the end of the cylindrical portion 1301 that is the bent portion, that is, as the depth of the cylindrical portion 1301 increases. With such a configuration, it becomes easy to fit other parts to the protruding part 1303 of the casing molded part 1300 that is bent inward of the cylindrical part 1301. The molded component for casing 1300 according to the present embodiment includes a rib in the vicinity of the bent portion 1305 on the outer periphery of the cylindrical portion 1301.
