PURPOSE:To prevent a carriage from being displaced obliquely, by making a detaining part abut with a sub rail, even when a pressing force is applied on the pedestal of the carriage, at the time of connecting an arm on the carriage with a screw. CONSTITUTION:At the side edge of a sub rail 4 side near the pedestal 1a of a carriage 1, a detaining projection 1f to about with the sub rail 4 only when screws 9a and 9b are screwed, is provided. The detaining projection 1f is abutted with the sub rail 4, and the oblique displacement of the carriage 1 can be suppressed at at a minimum, even when the main rail guide 1b of the carriage 1 is inserted to a main rail 3, and also, the screws 9a and 9b are screwed with a driver D in a state where the sub rail 4 is caught by a sub rail guide 1c. Therefore, since no twisted deformation is generated in the main rail 3, and a plate body 5, aberration between a magnetic head 2, and a magnetic head 6 can be evaded at the time of unfastening the driver D after completing screwing. |
