Abstract:
To provide a hole plug which can be easily removed from a screw hole at maintenance while securing a high holding force for preventing a fall from the screw hole at a normal time.SOLUTION: A hole plug 2 in which a plurality of hole plug bodies 3, 4 are connected to each other is constituted of the first hole plug body 3 and the single or plurality of second hole plug bodies 4 which adjoin the first hole plug body 3. A first holding force acting on a first support column part 12 of the first hole plug 3 attached to a screw hole 1a of a mating member 1 is set high so that the first support column member 12 is broken when the first support column part 12 is withdrawn from the screw hole 1a. Also, a second holding force acting on a second support column part 22 of the second hole plug body 4 attached to the screw hole 1a of the mating member 1 is set low so that the second support column part 22 is not broken even if the second support column part 22 is withdrawn from the screw hole 1a. A relationship of the first holding force>the second holding force is established.SELECTED DRAWING: Figure 8
