<p>PURPOSE:To prevent the abnormal condition of a cover by forming a canopy part at the side away from the shaft part of a main body, and providing a handling part at the protective cover side and a middle part having elasticity to link the key part and the shaft part. CONSTITUTION:The cover has a recessed part 10 to match with a projected part 9 of the lower part of a front cover 2 fixed at a main body 1, and is composed of a shaft part 14 to fit freely turnably with a key part 12, a middle elasticity part 13 and a front cover 2 having the canopy part 8 and a space 11. At the time of opening, by pushing the key part 12 from upward, the key part 12 descends for the space 11 only, the recessed part 10 also descends interlockedly, and thereby, the hanging with the projected part 9 of the front cover 2 is slipped off, and a cover 5 can be opened. The force from upward to the key part 12 is absorbed by the elastic change of the middle part 13. Thus, the cover, which is low in price secured to have no fault, can be obtained.</p> |
