  In the figure, the cab ceiling is composed of a canopy portion 1 and a ceiling design surface 2, and a translucent acrylic resin lighting plate 4 is installed in an opening 3 formed in the center of the ceiling design surface 2. ing. An attachment portion formed integrally with the ceiling design surface 2 is attached to the upper surface of the side wall 5 of the cab. The lamp 6 is disposed above the opening 3 of the ceiling design surface 2 in the lamp house 7 located in the center of the space formed by the canopy portion 1 and the ceiling design surface 2. The upper horizontal piece upper surfaces of a pair of Z-shaped guide reinforcements 8 are fixed to the opposite side edges of the lower surface of the canopy 1, and the lower horizontal pieces face each other to form a guide rail. The guide reinforcement 8 is arranged in parallel in the vicinity of the two opposing surfaces of the side wall that is integrally formed upright from the edge of the ceiling design surface 2 outside the lamp house 7.

  A long and narrow guide body 9 having a downward U-shape is placed between the upper surfaces of the lower horizontal pieces of the pair of guide reinforcements 8. The guide body 9 is disposed in the vicinity of a side wall integrally formed upright from the edge of the ceiling design surface 2 outside the lamp house 7 so that the longitudinal direction thereof is orthogonal to the longitudinal direction of the guide reinforcement 8. A guide portion 10 made of a material such as resin or rubber is provided at the tip of the placement portion of the guide body 9 that comes into contact with the guide reinforcement 8 so that the guide body 9 can be smoothly slid. The connecting portion is horizontally disposed in the vicinity of the lower surface of the canopy portion 1. The height of the guide body 9 is set lower than the space height determined by the lower surface of the canopy 1 and the upper surface of the lower horizontal piece of the guide reinforcement 8, which contributes to the thinning of the cab ceiling.

  Upper horizontal pieces of a pair of Z-shaped mounting bases 11 are fixed to the lower surfaces near both ends of the connecting portion of the guide body 9 by fastening screws 12 from above. The lower horizontal piece of the pair of fixing plates 13 is detachably attached to the lower surface of the lower horizontal piece of the pair of mounts 11 from below with a fastening screw 14. On the lower surface of the upper horizontal piece of the pair of fixing plates 13, an elongated ballast or a flange portion on the top of the inverter 15 is fixed from above by a fastening screw 16, and the longitudinal direction thereof is aligned with the longitudinal direction of the guide body 9.
