Claims

[Claims for Utility Model Registration] A linear guide device consisting of a guide rail fixed to a base and a slider fitted into the guide rail and movable in the axial direction through the rolling of a large number of rolling elements. , a table feeding device comprising a table fixed to a slider of the linear guide device, and a linear drive means for linearly moving the table, the linear drive means being arranged parallel to the guide rail and attached to the base. It consists of a fixed rack, a pinion that meshes with the rack, and a rotation drive means having a housing fixed to the table and rotating the pinion, and the rotation drive means includes a motor stator fixed to the housing, and a rotation drive means that rotates the pinion. a motor rotor facing each other and coaxially arranged in a housing; an output shaft fixed to the motor rotor, extending in the axial direction, rotatably supported by the housing via a bearing, and directly fixed to the pinion; A table feeding device characterized in that it is a direct drive type rotation drive means comprising a rotation detector for detecting a rotation angle of the output shaft.
