A vehicle includes a vehicle cabin, a storage chamber, and a partition wall separating the storage chamber from the vehicle cabin. The storage chamber is arranged on at least one side of the vehicle cabin in the vehicle front-rear direction. The partition wall has an opening and the storage chamber communicates with the vehicle cabin via the opening. A cover configured to open and close the opening is provided over the opening. A brake fluid pressure generation device is stored in the storage chamber. The brake fluid pressure generation device includes a reservoir tank in which hydraulic fluid is accumulated and is arranged at a position facing the opening.
