1. A work vehicle, comprising: a cassette gas cylinder;a cylinder mount in which the cassette gas cylinder is installed; andan engine driven by fuel supplied from the cassette gas cylinder,wherein the cylinder mount comprises a mouthpiece support for supporting a mouthpiece of the cassette gas cylinder, and a shutter member vertically swingable about a support shaft provided to the cylinder mount, for opening and closing an opening in the mouthpiece support from above the mouthpiece support. 2. The work vehicle of claim 1, wherein the cylinder mount further comprises cylinder-holding means capable of switching the cassette gas cylinder between a held state and a released state, and shutter-interlocking means designed to switch the shutter member to an opened state in conjunction with an operation of the cylinder-holding means as the cassette gas cylinder is switched from the held state to the released state. 3. The work vehicle of claim 2, wherein the shutter-interlocking means comprises a locking member capable of locking with the cylinder-holding means disposed in a cassette-gas-cylinder holding position, so that by locking of the locking member with the cylinder-holding means, the shutter member is switched to an open state in conjunction with the operation of the cylinder-holding means as the cassette gas cylinder is switched from the held state to the released state. 4. The work vehicle of claim 2, wherein the cylinder mount comprises a support bracket for supporting the cylinder-holding means, and a holding force generator obtained by making part of the support bracket elastically deformable, and creating elastic deformation in the holding force generator causes a holding force to be generated for holding the cassette gas cylinder in the cylinder mount. 5. The work vehicle of claim 1, wherein the cassette gas cylinder is designed to be housed in a gas cylinder case, the cylinder case being halved into a pair of cases, the pair of cases is linked in an openable and closeable manner by a hinge pin of a hinge provided to the pair of cases, and the hinge has stoppers for preventing the hinge pin from falling out.
