20, at 20 deep position.In addition, the angle of taper B of front end side pin 4 is small, therefore, compared with rotation tool 101, can inhibit to
Under Plastic Flow.Thus, it can prevent from being formed with kiss in the lower part of plastification region W and connect.On the other hand, the cone of base end side pin 3
Angle angle A is big, therefore, compared with existing rotation tool, even if being become by the thickness of jointing metal component, jointing altitude position
Change, also can steadily engage.
In addition, can be pressed by the outer peripheral surface of base end side pin 3 Plastic Flow material, therefore, it can reduce and be formed in
The groove of engagement surface, and can eliminate or reduce the protrusion being formed near groove.In addition, stair-stepping layers of difference portion 10 is shallow
And outlet is big, therefore, is pressed using layer difference bottom surface 10a Plastic Flow material, while Plastic Flow material being made to be easy to arrange
The outside of layers of difference portion 10 is arrived out.Thus, even if being pressed by base end side pin 3 Plastic Flow material, Plastic Flow material

Embodiment
Then, the embodiment of the present invention is illustrated.In embodiment, these three tests of embodiment 1,2,3 are carried out, and
Engagement surface roughness after friction-stir process is measured.
[embodiment 1]
In embodiment 1, tool 1 will be rotated to be inserted into from the front of single metal component (aluminium alloy: A5052-H34), and made
It relatively moves predetermined distance, and the plastification region generated after friction-stir, passes through rough surface meter (main body: サ ー
Off U system (surfcom) 1400D, controller: KA9801CF) surface roughness Rz (μm) is measured.Measuring condition is based on
Measurement length is set as 5mm, measuring speed is set as 0.6mm/s, truncation classification (Japanese: カ ッ ト オ Off species) is set by JIS01
For Gauss, cut-off wavelength (Japanese: カ ッ ト オ Off wavelength) is set as λ s=0.8mm.The width of metal component is set as 100mm,
It is 300mm by length, is 2mm by plate thickness.The revolving speed of rotation tool 1 is set as 5000rpm, engaging speed is set as 500mm/ points
Clock.The insertion depth for rotating tool 1 (from the front end of rotation tool 1 to the positive distance of metal component) is set as 1.8mm.It will
The layer declinate degree C of layers of difference portion 10 is 90 °.It is 75 ° by the angle of taper B of front end side pin 4.By (the ginseng of helicla flute 11 of front end side pin 4
According to Fig. 2) distance X2 be set as 0.18mm, height Y2 is set as 0.22mm.The length of front end side pin 4 is set as 1mm, by front end
Diameter is set as 2mm (the above are primary conditions).
As shown in Figure 10, in embodiment 1, make the base end side pin 3 of rotation tool 1 angle of taper A change for 105 °,
120 °, 135 °, 142.5 °, 150 °, 157.5 °, 165 °, and to the correlativity between angle of taper and engagement surface roughness
It is investigated.Distance X1 is set at essentially fixation, and the height Y1 of the layer difference side 10b of layers of difference portion 10 at this time is as shown in Figure 10.
That is, the height Y1 of layer difference side 10b becomes smaller as angle of taper A becomes larger.
As shown in figure 11, it is known that if the angle of taper A of base end side pin 3 is 135 °~160 °, surface engages roughness meeting
Become smaller.It knows when angle of taper A is less than 135 °, there are bigger tendencies for engagement surface roughness.When angle of taper A is less than
At 135 °, become the form of the tool close to no shaft shoulder, it is therefore contemplated that the effect pressed Plastic Flow material disappears
It loses, engagement surface roughness becomes larger.On the other hand, when angle of taper A is greater than 160 °, height Y1 becomes smaller, the layer of layers of difference portion 10

[embodiment 2]
In example 2, as shown in figure 12, angle of taper A is fixed on 150 °, make layer difference side 10b height Y1 change be
0.05mm, 0.10mm, 0.18mm, 0.25mm, 0.33mm, 0.40mm, and it is thick to the height Y1 and engagement surface of layer difference side 10b
Correlativity between rugosity is investigated.Other conditions other than angle of taper A and height Y1 are basic with embodiment 1
Condition is identical.
In addition, in example 2, as shown in figure 13, using comparative example shown in patent document 2 rotation tool 200 into
Row friction-stir.The rotation tool 200 of comparative example includes base end side pin 203 and front end side pin 204.The cone angle of base end side pin 203
Angle B is bigger than the angle of taper of front end side pin 204.Spiral helicine slot 13 is formed in the outer peripheral surface of cardinal extremity pin 203.Slot 13 is cut
Face shape is in substantially semi-circular.The radius of curvature of slot 13 is set as 0.5mm.The depth of slot 13 is set as 0.3mm, adjacent slot 13,13
Distance be set as 1.2mm.In front end side, the outer peripheral surface of pin 204 is formed with helicla flute 11.
As shown in figure 14, it is known that if the height Y1 of layer difference side 10b is 0.10~0.40mm, engagement surface roughness becomes
It is small.In the rotation tool 200 of comparative example, engagement surface roughness is 55 μm.If height Y1 known to is 0.05mm, table of joint
Surface roughness significantly becomes larger.If height Y1 is less than 0.10mm, then it is assumed that due to the state close to no layer difference, it is based on
The Plastic Flow amount of layers of difference portion 10 is reduced, and engagement surface roughness becomes larger.
On the other hand, if height Y1 is greater than 0.40mm, there are engagement surface roughness bigger tendencies.If height Y1 becomes
Greatly, then the distance X1 of layer difference bottom surface 10a will necessarily become larger.For example, distance X1 is dramatically increased if angle of taper A is greater than 150 °.
If the distance X1 of layer difference bottom surface 10a becomes larger, effective layers of difference portion quantity under identical insertion depth (connects with by jointing metal component
The quantity of the layers of difference portion of touching) it can reduce, it is therefore contemplated that the Plastic Flow amount based on layers of difference portion 10 is reduced, engagement surface roughness
Become larger.In addition, make 1 pair of rotation tool to be implemented by the pressing force variation of jointing metal component for 2600N, 2800N, 3000N, but
Difference is hardly visible under pressing force.
[embodiment 3]
In embodiment 3, as shown in figure 15, make a layer declinate degree C variation, and between layer declinate degree C and engagement surface roughness
Correlativity investigated.In embodiment 3, angle of taper A is set as 150 °.Layer declinate degree C variation for 60 °, 75 °,
85°,90°,105°,120°,135°.In addition, the case where the height Y1 of layer difference side 10b is set as 0.1mm, is embodiment 3-
1, as embodiment 3-2 the case where height Y1 is set as 0.18mm, as embodiment 3- the case where height Y1 is set as 0.25mm
3.Other conditions are identical as the primary condition of embodiment 1.
As shown in Figure 16~Figure 18, it is known that if layer declinate degree C is set as 85 °~120 °, engagement surface roughness becomes smaller.
If layer declinate degree C less than 85 °, is easy to accumulate Plastic Flow material in the inside of layers of difference portion 10, Plastic Flow material is attached to
The inside of layers of difference portion 10, and can not play a role as layers of difference portion 10.In addition, if Plastic Flow material is attached to layers of difference portion 10,
It above-mentioned Plastic Flow material and may then be damaged by jointing metal component.On the other hand, if layer declinate degree C is more than 120 °,
