Is substantially constant in the pressing direction. At this time, the vibration welding rib 91d of the first inclined joint portion 82 has a height H · cos θ in the vertical direction of the inclination direction. And FIG.
As shown in the above, by applying the pressing force F, F 0 ,
The first and second flat joints 81 and 83 and the first and second inclined joints 82 and 84 are brought into contact at the same time. Further, in this state, by applying a reciprocating vibration v perpendicular to the paper surface (parallel to the paper surface in FIG. 23), the vibration welding rib 91d shown in FIG. 23 is melted to about the two-dot chain line, and as shown in FIG. First and second planar joints 81 and 83 and first and second inclined joints 8
A vibration welding joint region V in a softened state is formed at 2, 84. Thereafter, the reciprocating vibration v is stopped, and the vibration welding joint region V is solidified by the temperature drop over time. Thus, the first,
The two-plane joints 81 and 83 and the first and second inclined joints 82,

ば、表1が得られる。The welding margin 90 of the vibration welding rib 91d in the resin manifold is shown by hatching in FIG. The welding allowance 90 has a depth h (h <H) at the first and second planar joints 81 and 83, but the first and second inclined joints 82 and 84.
Then, the pressing direction is the depth h, and the vertical direction of the inclination direction is the depth h.
-It becomes cosθ. Here, by adjusting the pressing forces F and F 0 , the depth h of the welding margin 90 at the first and second flat joints 81 and 83 is set to 1.5 mm, and the inclination angle θ
Is in the range of 0 to 90 °, the first and second inclined joints 8
Table 1 is obtained by comparing the depth h · cos θ of the welding margin 90 at 2, 84.

代90が低下することがわかる。[Table 1] From Table 1, the resin-made intake manifold has the first and second flat joints 8.
Even if the welding margin 90 at 1, 83 is sufficiently secured, the inclination angle θ
It can be seen that the welding margin 90 at the first and second inclined joints 82 and 84 decreases as the number increases.

FIG. 22 shows that the smaller the welding margin 90, the lower the tensile strength. For this reason, when the joining strength of the first and second inclined joining portions is not sufficient,
It can be seen that the first and second inclined joints are easily broken. For example, if the resin product is a hollow product such as a resin intake manifold, the resin product may be broken when the internal pressure is large.

必要を生じる。As a second problem, if the welding margin 90 at the first and second inclined joints 82 and 84 is not sufficiently ensured, the welding at the first and second flat joints 81 and 83 will be required. 90s
As shown in FIG. 24, the burrs 6 generated at the first and second flat joints 81 and 83 become the first and second inclined joints 8.
Since the number of burrs is increased as compared with the burrs 6 generated at 2 and 84, it is necessary to increase the burr storage space C secured by the concave portions 91e and the like.

要以上に増加させないことを目的とする。For this reason, the width of the first and second flat joints becomes large, and the resin product becomes excessively large, which limits the design conditions. For example, if the resin product is such a resin intake manifold, the degree of freedom in the engine room is limited. SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional circumstances, and is a resin product by joining first and second joining resin members having first and second planar joining portions and first and second inclined joining portions. It is an object of the present invention to make the joint strength of the resin product sufficient and not to increase the burrs generated at the first and second flat joints more than necessary.

It can be seen that when the depth h of the welding margin 90 is small, the pressure resistance is small. Therefore, it is understood that the set welding margin 90 must be increased in the conventional manufacturing method. On the other hand, in the manufacturing method according to the first embodiment, the joining strength at the first and second planar joining portions 81 and 83 and the joining strength at the first and second inclined joining portions 82 and 84 are substantially equal.
