Direction tilts, and is formed as cup-shaped.Wall 113a is an example of peripheral wall.
Here, as shown in figure 5, the thickness of wall 111a is t1, the thickness of wall 112a, 112b are t3, and the thickness of wall 113a is
t2.In addition, though do not illustrate, but the thickness of wall 112c is also t3.T3 is more than t1, and t2 is more than t3 (t1 ＜ t3 ＜ t2).Wall
111a is an example of the first wall, and wall 112a, 112b, 112c are an examples of third wall, and wall 113a is the one of the second wall
A example.
It is shown in Fig. 6 and is provided with the region A1 for the wall 111a (end wall) that thickness is t1, is provided with the wall that thickness is t3
112a (end wall), 112c region A31, be provided with thickness be t3 wall 112b (peripheral wall) region A32 and be provided with thickness
For the region A2 of the wall 113a (peripheral wall) of t2.It will be appreciated from fig. 6 that in first shell 110, region A31 is to be clipped in region A1 and area
Mode between the A2 of domain configures.Configuration in this way, the case where constituting first shell 110 by casting (such as aluminium die casting)
Under, such as in region A2 setting cast gates, to which the metal material with mobility can hinder in high and flowing from the height in mold
The part that height of the small part of power into mold is low and flow resistance is big, i.e., from the part of forming region A2, via formation area
The part of domain A31 is flowed to the part of forming region A1, so the metal material with mobility can be more smooth in mold
It flows on ground.
It as described above, in the present embodiment, can be right such as in first shell 110 (case of transmission 100)
The size for the torque that should be acted on configures three different walls 111a, 112a, 113a of thickness.Therefore, according to this structure, first
Shell 110 or even speed changer 1 can ensure required rigidity and intensity and more lightly constitute.
In addition, in the present embodiment, such as wall 112a (third wall) includes being located at wall 111a (the first wall) and wall 113a
The position of countershaft supporting part 115b adjoinings between (the second wall) and with bearing countershaft 18.Therefore, according to this structure, such as
In the casting process of first shell 110 (case of transmission 100), can make to have in mold the metal material of mobility by
According to the high sequence of height, i.e., according to the part for forming the part of wall 113a, forming the part of wall 112a and forming wall 111a
Sequential flowing.Therefore, the metal material with mobility can be made more swimmingly to be flowed in type, can inhibiting to be molded bad
Generation.
In addition, in the present embodiment, such as wall 111a (the first wall) or wall 112b (third wall) be provided with rib
114.Therefore, according to this structure, rib 114 can be utilized to reinforce the wall 111a or wall thinner than wall 113a (the second wall)
112b.First shell 110 can more effectively be reinforced using rib 114.
In addition, in the present embodiment, such as first shell 110 (case of transmission 100) has and the extension of input shaft 15
Orthogonal wall 111a (end wall) of direction Ax (first direction), adjacent with wall 111a and tilted relative to direction Ax and than the wall
The wall 112b (peripheral wall) of 111a thickness.In addition, first shell 110 has the wall 112a (end wall) orthogonal with direction Ax and wall 112a
It abuts and relative to direction Ax inclinations and the wall 113a (peripheral wall) thicker than wall 112a.Because the stress that torque generates holds on peripheral wall
It is easily higher than end wall.Therefore, according to this structure, first shell 110 or even speed changer 1 can ensure required rigidity and intensity
And it more lightly constitutes.
More than, instantiate embodiments of the present invention, the above embodiment is an example, and the model of non-limiting invention
It encloses.The above embodiment can be implemented by various other modes, can be carried out in the range of not departing from invention objective each
Kind is omitted, displacement, combination, is changed.The above embodiment is contained in the range of invention, objective, and is contained in and patent right
In the invention of claim record and its equivalent range.The present invention can be by addition to structure disclosed in the above embodiment
Mode is realized, and can obtain the various effects (including derivative effect) obtained by basic structure (technical characteristic).Separately
Outside, specification (construction, type, direction, shape, size, length, width, thickness, height, quantity, configuration, the position of each structural element
Set, material etc.) it can also suitably change to implement.Such as the present invention can be applied not only to manual transmission, apply also for
Double-clutch speed changer (DCT), automatic transmission (AMT) etc..
The explanation of reference numeral
1 ... speed changer, 15 ... input shafts, 18 ... countershafts, 38 ... differential casings, 100 ... case of transmission, 110 ...
