<P>PROBLEM TO BE SOLVED: To provide an inspection port in which attachment and detachment operations of an inspection port cover are easy and the inspection port cover is not easily disengaged when a vibration such as an earthquake occurs. <P>SOLUTION: An inspection port 1 has an insertion engaging structure 8 by which an inspection port cover 5 slides and one side section side thereof is engaged with one side section side of an inspection port frame 4. The other side section side of the inspection port cover 5 is a so-called push-push type catch device 10 and is structured so as to be engaged with the inspection port frame 4. The inspection port cover can be attached to the inspection port frame by a very simple operation of sliding the one side section side of the inspection port cover 5 to the one side section side of the inspection port frame 4 and pushing the other side section side of the inspection port cover 5. Similarly, the inspection port cover can be detached from the inspection port frame by a simple operation. Since a base end part 11b of an engaging rod 11 is mounted in a mounting hole provided in the inspection port cover with play, there is little fear that an ampullar part 11a comes off a pair of catch pieces 16 because the base end part 11b of the engaging rod 11 follows a vibration such as an earthquake. <P>COPYRIGHT: (C)2013,JPO&INPIT |
