<p>PURPOSE:To perform simple and reliable rotation aside of a fuel tank, by a method wherein a spring is mounted to the pivotal support part of a fuel tank, and when the fuel tank is rotated to an upper limit, the fuel tank is moved horizontally to lock it to a support stand, and the fuel tank is prevented from down inclination. CONSTITUTION:A bracket 12 is secured to the central part of the front of a mission case 3 interlocked and coupled to an engine 2, and a pivotal support 13 is formed to the upper part of the bracket 12. A stay 11 formed integrally with a fuel tank 10 is rotatably mounted to the pivotal support part 13 by means of a pin 14. A plurality of vertical pieces 11a and 11b each having a hole in which the pin 14 is inserted are situated to the stay 11. Further, a compression spring 18 is located between the one vertical piece 11a and the pivotal support part 13, and the stay 11 is always energized toward the one side. After the fuel tank 10 is rotated upward around the pivotal support part 13, it is moved toward the one side through the force of the compression spring 18, and the vertical pieced 11b on the other side is locked to a notch part 21 of the bracket 12.</p> |
