Abstract
A safety device for a wall surface suction-type travel device that is configured to travel on a wall surface while being suctioned on the wall surface includes an extending member, a support base, and a safety rope. The extending member is configured to be disposed on the wall surface and bendable by self weight. The support base supports the extending member so as to allow the extending member to move in a direction along which the extending member extends. The safety rope connects the extending member with the wall surface suction-type travel device.
