Claims

[Claims for Utility Model Registration] A linear device for moving an object along a guide rail, in which a runner is moved and guided by the guide rail, and the object is connected to the runner and driven. In the motor, the guide rail is formed in a groove-shaped cross section through which the runner can be inserted in the longitudinal direction, and includes a side wall, a ceiling, and a bottom, and the guide rail has a polarity in the longitudinal direction along the side wall of the guide rail. Permanent magnets are arranged in a row in an alternating manner, and the runner is provided with a coil that faces the permanent magnets with a certain gap and is energized so as to be linearly driven by magnetic action between the permanent magnets and the permanent magnets. A guide portion is provided on the ceiling portion of the guide rail to restrain the upper portion of the runner so that it cannot move in both directions, and is capable of guiding the runner in the longitudinal direction, and a position regulating portion is provided on the bottom portion that extends in the longitudinal direction. A support roller is provided at the bottom of the runner that receives the load from the runner and can roll on the bottom when the runner moves, and a tapered roller with a wedge-shaped cross section is provided. What is claimed is: 1. A linear motor, characterized in that the tapered roller is movably mounted, the tapered roller is fitted into the long groove for position regulation, and is biased in the fitting direction.
