After opening the hole (later closed with a cap), it is necessary to insert a drill through the working hole. Therefore, it is not easy to form the neck hole at an accurate position and diameter, and if cuttings from the working hole enter the resonator, a special device is required to remove them. Note that the diameter and position of the neck hole determine the resonance frequency of the resonator, and accuracy is required.

スの製造方法に想到した。Means for Solving the Problems> In order to solve the above problems, the inventors of the present invention, in the process of making earnest efforts in development, developed a resonator by providing a joining flange portion on the outer periphery of each dividing surface and attaching the resonator to the upper part of the tank. I came up with the idea of dividing the bottom of the tank into two and welding the top of the tank together first when forming the hose blower. However, with this configuration, it was found that the joining flange interfered with the blow molding die during mold release, making it impossible to release the mold. Therefore, the present inventors made further efforts in development and came up with a method for manufacturing an air cleaner hose having the following configuration.

．． 13 on each dividing surface, and the upper side 2 of the tank, which includes the hose connection wall 4, and the lower side 12 of the tank are separately molded. The upper and lower sides 2.12 of each tank are then usually formed by injection molding.
ここで、溶接可能（熱又は振動溶接等による）な構成と
したのは、接着剤を使用する場合に比して、接着性のバ
ラツキが小さいことによる。Here, the reason why the structure is weldable (by heat or vibration welding, etc.) is because the variation in adhesiveness is smaller than when adhesive is used.

溶接容易なように、同種材料とし、さらに、ホース本体
２１とのブロー成形時の溶接性の関係から、ホース本体
成形材料（通常ポリオレフィン系）と同種材料とする。In addition, the molding materials for the upper and lower sides 2.12 of the tank are of the same type so that they can be easily welded to each other.Furthermore, due to the weldability during blow molding with the hose body 21, the molding material for the hose body (usually Use the same material as polyolefin (polyolefin).

る。In addition, the tank upper side 2 which is joined and integrated with the hose main body 21
In this case, a groove-shaped hose coupling wall 4, that is, a semicircular concave shape with an inner diameter corresponding to the outer diameter of the hose body 21, is formed on the coupling side with the hose body 21 (neck forming side). Note that a neck straight pipe 6 having an inner diameter and length that defines a resonance frequency is formed at the center of the lower surface of the hose joint wall 4.

可能となる。The joint M4 extends on both sides in the axial direction to form a joint wall extension part 5, and the extending end of the joint wall extension part 5 is located outside the protruding end of the joint flange part 3 on the tank upper side 2. It is located and formed. Specifically, the width b2 of the connecting wall extension part 5 is formed to be slightly longer than the width b1 of the joining flange part 3. With this configuration, when the hose body 21 is released from the mold after blow molding, the joining flange 3 on the tank upper side 2
It is possible to release the mold (removal table) without interfering with the blow molding die.

防止する構成としておくことが望ましい。A straight pipe receiving part 33a, which is an annular recess that receives the neck straight pipe 6 of the tank upper side 2, in the center of the set part 33, and a rectangular annular concave joint flange receiving part arranged around the straight pipe receiving part 33a (front, rear, left and right). 33b, at this time, a protruding cutter blade (not shown) is formed over the entire circumference on the end face of the split mold for setting the tank upper side 2, but the height of the cutter blade is is adjusted to be lower in the tank upper set part 33 than in other parts (for example, 0.8 times lower than the wall thickness of the joint wall extension part), and presses the cut-out part of the joint wall soil in the mold clamping state. It is desirable to have a structure that prevents blow-out during blow molding.
なお、タンク上側２のホース結合Ｍ６が下面に直管を有
しない場合は、ＴＳ６図に示す如く、直管受容部は不要
である。Note that if the hose connection M6 on the upper side of the tank 2 does not have a straight pipe on the lower surface, the straight pipe receiving part is not required as shown in Figure TS6.

At this time, if the resonator coupling part 22 is to be formed of hard plastic and the other parts, the bellows part 23 and the terminal part 24 are to be formed of soft plastic, each part of the parison may be The parts to be formed are extruded in multiple colors using various materials, and the plastic materials of the tank upper side 2 and the parison are made of the same material, and both members are heat welded using the heat of blow molding.

Specifically, the inner periphery of the straight pipe connection portion on the tank upper side 2 of the hose main body 21 is cut out to form a sekiguchi state. At this time, since there are no obstructions and the drilling work can be carried out directly, it is possible to drill a hole with an accurate diameter. Further, even if there is no straight pipe, the neck hole 7 can be easily formed at an accurate position. Furthermore, even if cutting debris falls into the hose body 21, it can be easily removed by air blowing.

The neck hole can be drilled with good workability, and in the present invention, the resonator neck hole can be drilled at an accurate position.
It becomes easy to finish the diameter. Further, since there is no need to form a hole for drilling, there is no need to consider the possibility that cutting waste remains inside the resonator.

A method for manufacturing an air cleaner hose in which a resonator and a hose body are welded together through a hose joint wall during molding, and then a resonator neck hole is formed in a partition wall between the resonator and the hose body, wherein the resonator is weldable. A connecting flange portion is provided on each dividing surface, and the upper side of the tank having the hose connecting wall and the lower side of the tank are formed separately and then welded together via the connecting flange portion, and , the hose connection wall extends on both sides in the axial direction to form a connection wall extension part, and the extension end of the connection wall extension part is located outside the protruding end of the connection flange part. A method for manufacturing an air cleaner hose characterized by:
