Therefore, radiator 51 can blocked with the bottom plate 35 of concentrated setting, fluid reservoir 36, motor 37, oil pump 38 and accumulator 39
After impact load, impact load is disperseed using bottom plate 35, fluid reservoir 36, motor 37, oil pump 38 and accumulator 39.
As a result, bottom plate 35 can more effectively be inhibited to deform, excessive load can be more efficiently prevented from from bottom plate
35 are transmitted to case of transmission 2.
In addition, according to the automatic transmission 1 of the present embodiment, it is accommodated in case of transmission 2：Input shaft 6, power is from interior
Combustion engine 50 is transmitted to input shaft 6；And clutch 5 and gearshift chosen axis 10, the power of internal combustion engine 50 is transmitted to defeated by clutch 5
Enter axis 6 or blocked transmitting, gearshift chosen axis 10 carries out gear shift operation.
The clutch separation component 20 of hydraulic operation clutch 5 generated by oil pump 38, clutch are equipped on input shaft 6
Separating member 20 is connect with accumulator 39 by oil pressure piping 23.
Bottom plate 35 has working oil supply unit 35D, and working oil supply unit 35D is connected to oil pressure piping 23, by accumulator 39
Working oil oil feed pressure piping 23 is provided.Working oil supply unit 35D be arranged in the vehicle width direction motor 37 and oil pump 38 with
Between accumulator 39, and it is set to the front end face 38a positions rearward of the front end face 37a and oil pump 38 than motor 37.
It can make radiator 51 and storage before radiator 51 is rearward moved and contacted with working oil supply unit 35D as a result,
Flow container 36, motor 37 and oil pump 38 contact.Therefore, it can mitigate from radiator 51 and be applied to rushing for working oil supply unit 35D
It hits, working oil supply unit 35D can be protected and working oil is made to be not easy to leak out.
In addition, according to the automatic transmission 1 of the present embodiment, it is accommodated in case of transmission 2：1st jackshaft 7 leads to
It crosses input gear 6A and the 1st countershaft-gear 7A links with input shaft 6；2nd jackshaft 8, by input gear 6A and the 2nd
Between shaft gear 8A link with input shaft 6；And end driven gear 9A, the power of the 1st jackshaft 7 and the 2nd jackshaft 8 are transmitted to
End driven gear 9A.
As a result, in order to ensure the installation space of input shaft 6, the 1st jackshaft 7 and the 2nd jackshaft 8, chosen axis 10 of shifting gears
Front is arranged on Deng relative to input shaft 6, the 1st jackshaft 7 and the 2nd jackshaft 8.Therefore, when radiator 51 and transmission case
When body 2 collides, it is possible to apply big impact to gearshift chosen axis 10.
In this regard, the automatic transmission 1 of the present embodiment can make radiator 51 and liquid storage when frontal collisions occur for vehicle 100
Tank 36, motor 37, oil pump 38 and accumulator 39 contact and prevent from applying case of transmission 2 excessive impact, therefore energy
Protection gearshift chosen axis 10 etc..
In addition, according to the automatic transmission 1 of the present embodiment, jackshaft includes the 1st jackshaft 7 and the 2nd jackshaft 8 this 2
Axis, therefore automatic transmission 1 can be minimized and can easily protect automatic transmission 1.
