徴とする測長装置。A linear scale provided with a scale in the longitudinal direction, a holder for storing the linear scale, a moving member movable along the longitudinal direction of the linear scale, and a moving member that engages with the linear scale and is connected to the moving member. A holder for storing the linear scale has an opening in the longitudinal direction, and an arm of the moving member enters the holder through the opening from the outside of the holder. In a length measuring device in which the reading head is connected to this arm and the opening is closed by a sealing means, gas is supplied into the holder from at least one of the holder side ends, and the pressure inside the holder is lower than the external pressure. A gas supply means for increasing the height is provided, and a gas outlet of the means is disposed at at least one of the holder side ends so that the gas is injected in the longitudinal direction of the linear scale, and a gas outlet of the means is provided in front of the gas outlet. 1. A length measuring device comprising a shielding plate that shields a gas path and makes the gas flow path parallel to both sides of the linear scale.
