What is claimed is: 1. A vehicular pop-up hood device comprising: a cylinder; a piston rod that can protrude from a front end of the cylinder; a gas generator to urge the piston rod, the gas generator provided at a side of a rear end of the cylinder; and a bracket to attach the cylinder to a vehicle body, wherein the bracket includes a top portion engaged with the front end of the cylinder, an overhanging portion for attachment to the vehicle body, the overhanging portion overhanging from the cylinder in a direction intersecting with an axial direction of the cylinder, and, the bracket includes a connection portion continuous to the top portion, extending along the cylinder, and connecting the overhanging portion with the top portion. 2. The vehicular pop-up hood device according to claim 1 , wherein the front end of the cylinder is welded with the top portion. 3. The vehicular pop-up hood device according to claim 1 , further comprising a front-end-side cover part covering a front end portion of the vehicular pop-up hood device and made of hot-melt synthetic resin. 4. The vehicular pop-up hood device according to claim 1 , further comprising a rear-end-side cover part covering a rear end portion of the vehicular pop-up hood device and made of the hot-melt synthetic resin. 5. The vehicular pop-up hood device according to claim 4 , further comprising a harness continuous to the gas generator that is routed in a direction toward the front end of the cylinder along an outer surface of the cylinder, and wherein the harness is embedded in and fixed to the rear-end-side cover part. 6. The vehicular pop-up hood device according to claim 4 , wherein a harness is continuous to the gas generator, and a connector portion of the harness connected with the gas generator is embedded in the rear-end-side cover part and is pushed in at a side of the gas generator. 7. The vehicular pop-up hood device according to claim 1 , further comprising a front-end-side cover part covering a front end portion of the vehicular pop-up hood device. 8. The vehicular pop-up hood device according to claim 1 , further comprising a rear-end-side cover part covering a rear end portion of the vehicular pop-up hood device. 9. A vehicular pop-up hood device comprising: an actuator including a cylinder, a piston rod that can protrude from a front end of the cylinder, and a gas generator to urge the piston rod, the gas generator provided at a side of a rear end of the cylinder; and a bracket to attach the actuator to a vehicle body, wherein the vehicular pop-up hood device includes a rear-end-side cover part covering a rear end portion of the vehicular pop-up hood device and made of hot-melt synthetic resin, wherein a harness continuous to the gas generator is routed along an outer surface of the cylinder in a direction toward the front end of the cylinder, and wherein the harness is embedded in and fixed to the rear-end-side cover part.
