Abstract
A laser gradient setting device, which comprises a swing frame rotatable around a vertical shaft, a laser projector tiltably mounted on the swing frame via a support member so that it is tiltable around a horizontal shaft, a tilt sensor mounted independently from the laser projector and rotatably around the horizontal shaft, an encoder integrally rotating with the tilt sensor, a vertical angle adjusting means for tilting the support member, and a tilt sensor tilting means mounted on the support member and for tilting the tilt sensor, whereby the tilt sensor is tilted so that the tilt angle detected by the encoder agrees with the preset gradient and the tilt sensor is integrally tilted with the laser projector so that the tilt sensor is held horizontally.
