  "textContent": "A battery forklift includes a battery and a motor that includes a rotation shaft and is driven using the battery as a power source. A reduction device reduces the speed of rotation of the rotation shaft and transmits the rotation to an axle. A case accommodates the reduction device. A drive wheel is driven by rotation of the axle. The reduction device includes a helical gear rotated integrally with the rotation shaft and a drive shaft formed integrally with the helical gear and extended in a vertical direction. The reduction device further includes an upper bearing located above the helical gear to support the drive shaft rotatably relative to the case and a lower bearing located below the helical gear to support the drive shaft rotatably relative to the case. The case includes a communication portion that communicates a lower void located below the upper bearing and an upper void located above the upper bearing.",
