PROBLEM TO BE SOLVED: To improve reliability in the sliding operation of a lid regardless of the change in external temperature. SOLUTION: This electronic device is provided with a base body 3 having a base surface 6a formed planar, a lid body 2 supported on the base body to freely slide and made of a material having a thermal expansion factor different from that of the base body, a fed part 4 disposed in the end of the base surface side of the lid body, feeding parts 30 and 30 disposed in the feed rollers to support the feed rollers 28 and 28 engaged with the fed part of the base body through support shafts 34 and 34 and to move in the axial direction of the support shafts, slope contact surfaces 30d and 30d formed on the outer peripheral surfaces of the feeding parts to be inclined with respect to the support shafts and to be engaged with the fed part, and energizing springs 32 and 32 for energizing the slope contact surfaces in the direction of adhering to the fed part.
