Fork shaft, it is provided with selector fork.Also, it is configured to：Make axial movement of the sleeve with sliding selector shaft using selector fork
And slide axially, it is consequently formed defined gear.
But in the selector fork of sychronisation as described above, if the rigidity of shift fork axle (is directed to the bending of load
Rigidity) it is low, then the change deformation of the shift fork axle caused by load is big, causes so as to cause the switching of gear that delay occurs
Response reduces.Especially, because high performance sport car requires the contour driveability of acceleration, therefore it is required that gear is rapid
Switching.Therefore high rigidity must be had according to the Functional Requirement of vehicle side, shift fork axle.
But as making shift fork axle that there is the method for high rigidity, if thickening shift fork axle, shift fork axle can be caused
And the weight increase of selector fork.When the weight increase of shift fork axle and selector fork, shift fork axle and selector fork can be hindered suitable
Freely act, the response for switching gear is deteriorated.Based on it is such the reasons why, problem is to take into account shift fork axle and selector fork

In addition, described in patent document 2 in the prior art, caused by reducing the left and right imbalance of selector fork
Worn caused by inclined power and Yin Qi, make the section of shift fork axle there is anisotropy.That is, in length of arm of selector fork or so
In the case of different, make the rigidity in the section of shift fork axle there is anisotropy, so that the center extended along the most strong direction of rigidity
Line and the distance between the pawl of long arm are shorter than the distance between the pawl with galianconism portion, so as to improve the balance of rigidity.
But the purpose of the technology described in patent document 2 is the balance for adjusting selector fork, does not consider shift fork axle
The raising and lightweight of the rigidity of itself.According to the technology of patent document 2, even if selector fork does not produce partial wear etc., if
The rigidity of shift fork axle in itself is low, then still may be big the deformation of the shift fork axle caused by load, and causes cutting for gear
Raw delay is changed so as to cause response to decline.
