First claim
Opening claim text (preview).
The invention claimed is: 1 . A vehicle comprising: a battery; a battery case accommodating the battery; and a propeller shaft extending in a front-rear direction of the vehicle, wherein the propeller shaft is covered by a propeller shaft case, an internal space of the propeller shaft case communicates with an internal space of the battery case, and the vehicle is provided with at least one fire extinguishing hole communicating with the internal space of the propeller shaft case. 2 . The vehicle according to claim 1 , wherein the internal space of the propeller shaft case and the internal space of the battery case communicate with each other at communication parts, the vehicle comprises: electromagnetic valves each provided at a corresponding one of the communication parts; and a control device comprising one or more processors and one or more memories coupled to the one or more processors, and the one or more processors are configured to execute a process including controlling opening/closing operations of the electromagnetic valves. 3 . The vehicle according to claim 2 , wherein the one or more processors are configured to execute the process including controlling the opening/closing operations of the electromagnetic valves, based on information on a collision in the vehicle. 4 . The vehicle according to claim 3 , wherein the one or more processors are configured to execute the process including controlling the opening/closing operations of the electromagnetic valves, based on information on a temperature of the battery. 5 . The vehicle according to claim 2 , wherein the one or more processors are configured to execute the process including controlling the opening/closing operations of the electromagnetic valves, based on information on a temperature of the battery. 6 . The vehicle according to claim 1 , wherein the at least one fire extinguishing hole comprises fire extinguishing holes arranged at mutually different positions. 7 . The vehicle according to claim 6 , wherein the at least one fire extinguishing hole comprises a first fire extinguishing hole provided in a front wheel drive system case covering a front wheel drive system of the vehicle. 8 . The vehicle according to claim 6 , wherein the at least one fire extinguishing hole comprises a second fire extinguishing hole provided in a rear wheel drive system case covering a rear wheel drive system of the vehicle. 9 . The vehicle according to claim 6 , wherein the at least one fire extinguishing hole comprises a third fire extinguishing hole provided on a side of the vehicle. 10 . The vehicle according to claim 1 , wherein the at least one fire extinguishing hole comprises a first fire extinguishing hole provided in a front wheel drive system case covering a front wheel drive system of the vehicle. 11 . The vehicle according to claim 1 , wherein the at least one fire extinguishing hole comprises a second fire extinguishing hole provided in a rear wheel drive system case covering a rear wheel drive system of the vehicle. 12 . The vehicle according to claim 1 , wherein the at least one fire extinguishing hole comprises a third fire extinguishing hole provided on a side of the vehicle.
