  FIG. 11 is a cross-sectional view showing the main part of the fuel cell two-wheeled vehicle according to the present invention, taken along the line XI-XI in FIG.

  As shown in FIGS. 10 and 11, the bridge 37 of the fuel cell two-wheeled vehicle 1 according to the present embodiment is spaced from the fuel tank 5 at substantially equal intervals and is curved following the shape of the fuel tank 5. The bridge 37 includes a rear tank support portion 65 that supports the rear portion of the fuel tank 5. The rear tank support portion 65 serves as a guide when the fuel tank 5 is mounted on the vehicle body frame 6, and improves the retention of the fuel tank 5 mounted on the vehicle body frame 6.

  Each of the pair of left and right cross members 38 is detachably fixed to the down tube 35 and the pair of left and right main frames 32. The pair of left and right cross members 38 includes a side tank support portion 66 that holds the fuel tank 5 and a device support portion 67 that holds the fuel cell 2. The side tank support 66 supports the fuel tank 5, particularly the cylindrical body 59 at three points in cooperation with the rear tank support 65 of the bridge 37.

  The pair of left and right cross members 38 may sandwich an appropriate member or device other than the fuel cell 2 between the device support portions 67.

  FIG. 12 is a bottom view of the fuel cell motorcycle according to the present invention.

  13 is a cross-sectional view showing the main part of the fuel cell two-wheeled vehicle according to the present invention, taken along the line XIII-XIII in FIG.

  As shown in FIGS. 12 and 13, the fuel tank 5 of the fuel cell two-wheeled vehicle 1 according to the present embodiment is disposed substantially at the center in the vehicle width direction.

  On the other hand, the prime mover 3 is disposed so as to be biased toward one side (here, the right side) in the width direction of the vehicle with respect to the fuel tank 5 and a main body 68 that generates a driving force, and the fuel tank 5. And a drive sprocket 69 arranged to be biased to the other side (here, the left side) in the vehicle width direction, and a shaft 71 for transmitting a driving force from the main body 68 to the drive sprocket 69. The drive sprocket 69 transmits the driving force to the rear wheel 9 via a drive chain (not shown) to drive the fuel cell two-wheeled vehicle 1.

  The fuel cell two-wheeled vehicle 1 according to the present embodiment is a conventional one in which the longitudinal direction of the cylindrical fuel tank 5 is oriented in the longitudinal direction of the vehicle by arranging the longitudinal direction of the cylindrical fuel tank 5 parallel to the down tube 35. Compared with the fuel cell two-wheeled vehicle, the area occupied by the fuel tank 5 in the longitudinal direction of the vehicle can be reduced, the longitudinal length of the body frame 6 can be shortened, and the wheel base can be shortened. The fuel cell two-wheeled vehicle 1 according to the present embodiment can easily secure a longer extension / contraction length of the front fork 15 and an arm length of the swing arm 11 as long as the longitudinal length of the body frame 6 can be shortened. Can be improved.

  Further, the fuel cell two-wheeled vehicle 1 according to the present embodiment has a shape in which the fuel cell 2 extends substantially parallel to the down tube 35, so that the occupied area in the vehicle front-rear direction of the fuel cell 2 is reduced, and the front and rear of the vehicle body frame 6 are reduced. The length can be shortened and the wheelbase can be shortened. The fuel cell two-wheeled vehicle 1 according to the present embodiment further increases the expansion / contraction length of the front fork 15 and the arm length of the swing arm 11 (and hence the swing amount of the rear wheel 9) by the amount that the front and rear length of the body frame 6 can be shortened. It is easy to secure for a long time, and the operability of the vehicle can be improved.

  Furthermore, since the fuel cell two-wheeled vehicle 1 according to the present embodiment has the fuel cell 2 attached to the fuel tank 5, the relatively heavy fuel cell 2 and the fuel tank 5 are concentrated, and the moment of inertia at the time of turning of the vehicle is concentrated. This can contribute to a reduction in the operability and an improvement in operability.

  Furthermore, since the fuel cell two-wheeled vehicle 1 according to the present embodiment can be disposed with the fuel tank 5 close to the occupant, the body surface shape of the occupant's legs seated on the seat 13 and the abdomen is made smooth. Is possible and does not give the passengers a sense of incongruity.

  Further, in the fuel cell two-wheeled vehicle 1 according to the present embodiment, the prime mover 3 is arranged in a state where a part of the prime mover 3 is overlapped with a part of the fuel tank 5 in a side view of the vehicle body. The longitudinal length and vertical length of the vehicle can be shortened, and the relatively heavy motor 3 and the fuel tank 5 can be concentrated to reduce the moment of inertia when the vehicle turns, and thus improve the operability.

  Furthermore, since the fuel cell two-wheeled vehicle 1 according to the present embodiment has the fuel tank 5 disposed substantially at the center in the width direction of the vehicle, it is easy to suppress the weight deviation of the entire vehicle, thereby reducing the moment of inertia when the vehicle turns, and thus Contributes to improved operability.

  Furthermore, the fuel cell two-wheeled vehicle 1 according to the present embodiment biases the main body 68 of the prime mover 3 toward one side of the vehicle width direction with respect to the fuel tank 5 and biases the drive sprocket 69 toward either side. Therefore, the prime mover 3 and the fuel tank 5 can be concentrated to shorten the longitudinal length and the vertical length of the vehicle.

  Therefore, according to the fuel cell two-wheeled vehicle 1 according to the present embodiment, it is possible to achieve both good operability while providing a cylindrical fuel tank.

  Although the vehicle according to the present embodiment is the fuel cell motorcycle 1, the vehicle may be applied to a vehicle equipped with a high-pressure gaseous fuel tank such as LP gas or hydrogen gas.
