a housing unit in contact with the casing unit;
an input shaft support that is configured to support an input shaft, wherein the input shaft support is monolithically formed with the housing unit and comprises a lubricant flow path that is configured to receive a lubricant;
a first fastener coupling the casing unit and the housing unit to each other, wherein the first fastener is in direct physical contact with the casing unit and with the housing unit; and
a second fastener coupling the casing unit and the input shaft support to each other, wherein the second fastener is in direct physical contact with the casing unit and with the input shaft support,
wherein the input shaft support has an input shaft support coupling portion connected to the housing unit and coupled to the second fastener,
wherein the lubricant flow path comprises a first lubricant flow path and a second lubricant flow path, and
wherein the input shaft support comprises:
a first input shaft support extending away from the housing unit in a first direction that is parallel to an axial direction of the lubricant flow path, wherein the first input shaft support comes into contact with the casing unit, and wherein the first input shaft support comprises the input shaft support coupling portion and the first lubricant flow path; and
a second input shaft support connected to the first input shaft support, wherein the second input support shaft comprises the second lubricant flow path.
2. The transmission of claim 1 , wherein the casing unit comprises:
a first casing having a first casing coupling portion facing the housing unit, the first fastener being coupled to the first casing coupling portion; and
a second casing connected to the first casing, and
wherein the first input shaft support comes into contact with the first casing.
3. The transmission of claim 2 , wherein the housing unit comprises:
a first housing having a first housing coupling portion facing the first casing coupling portion, wherein the first fastener is coupled to the first housing coupling portion; and
a second housing extending away from the first housing, wherein the second housing is monolithically formed with the input shaft support, and
wherein the first input shaft support extends away from the second housing in the first direction.
4. The transmission of claim 3 , wherein the second casing has a second casing coupling portion, wherein the second fastener is coupled to the second casing coupling portion, and wherein the input shaft support coupling portion is connected to the second housing and faces the second casing coupling portion.
5. A transmission comprising:

a second fastener coupling the casing unit and the input shaft support to each other, wherein the second fastener is in direct physical contact with the casing unit and with the input shaft support,
wherein the input shaft support extends away from the housing unit in a first direction that is parallel to an axial direction of the lubricant flow path,
wherein the casing unit comprises:
a first casing having a first casing coupling portion facing the housing unit, the first fastener being coupled to the first casing coupling portion; and
a second casing connected to the first casing,
wherein the housing unit comprises:
a first housing having a first housing coupling portion facing the first casing coupling portion, wherein the first fastener is coupled to the first housing coupling portion; and
a second housing extending away from the first housing, wherein the second housing is monolithically formed with the input shaft support,
wherein the second casing has a second casing coupling portion, wherein the second fastener is coupled to the second casing coupling portion, wherein the input shaft support has an input shaft support coupling portion connected to the second housing and facing the second casing coupling portion, and wherein the second fastener is coupled to the input shaft support coupling portion,
wherein the lubricant flow path comprises a first lubricant flow path and a second lubricant flow path, and
wherein the input shaft support comprises:
a first input shaft support extending away from the second housing in the first direction, wherein the first input shaft support comes into contact with the first casing, and wherein the first input shaft support comprises the input shaft support coupling portion and the first lubricant flow path; and
