To provide a sound insulation structure of a cargo transport vehicle which can transport cargoes stored in a cargo box B on a vehicle body frame 1 to the outside and insulates sound noise emitted from a hydraulic drive device D which transports the cargoes to the outside.SOLUTION: In a sound insulation structure of a cargo transport vehicle, a hydraulic drive device D which transports cargoes is provided within a device storage housing 10 and an operation part 52 which may operate the hydraulic drive device D is provided at the outside of the device storage housing 10. A movable connection part 53 between the operation part 52 and the hydraulic drive device D penetrates through a through hole 55 of the device storage housing 10, and a sound insulation wall 58 facing in an orientation direction of sound noise emitted through the through hole 55 is provided at a noise insulation cover 57 provided at the device storage housing 10.SELECTED DRAWING: Figure 8
【課題】車体フレーム1上の荷箱B内に収容した積荷を外部に搬送可能とした積荷の搬送用車両の防音構造であって、積荷を搬送する油圧駆動装置Dより外部に発散する騒音を防音できるようにした。【解決手段】積荷の搬送用車両の防音構造であり、機器収容筐10内に積荷を搬送する油圧駆動装置Dを設け、機器収容筐10の外部に、油圧駆動装置Dを操作し得る操作部52を設け、操作部52と油圧駆動装置Dとの移動連結部53は機器収容筐10の通し穴55を貫通し、機器収容筐10に設けた防音カバー57には、通し穴55を通して発散する騒音の指向方向に対向する防音壁58を設けた。【選択図】図8
