Abstract: A wall surface suction-type travel device is configured to travel on a wall surface while being suctioned on the wall surface. An intermediate chamber communicates with decompression chambers facing the wall surface. A suction device sucks in air from the intermediate chamber to decompress the intermediate chamber. Principal communicating parts allow the decompression chambers to communicate with the intermediate chamber. Secondary communicating parts allow the respective decompression chambers to communicate with the intermediate chamber. Valves face openings of the respective principal communicating parts. An area of an opening of each of the secondary communicating parts is smaller than an area of the opening of a corresponding one of the principal communicating parts.

Abstract: A wall surface suction-type travel device includes a first travel unit, a second travel unit, a joint mechanism, and an elastic mechanism. The first and second travel units are aligned along a travel direction and are each configured to travel on a wall surface while being suctioned on the wall surface. The joint mechanism couples the first and second travel units together such that the travel units can pivot relative to each other on a pivot axis extending in a direction that is perpendicular both to a wall surface facing direction and the travel direction. The elastic mechanism includes a first end fixed to the first travel unit, a second end fixed to the second travel unit, and an elastic member configured to be elastically deformed when one of the first and second travel units pivots relative to the other travel unit and a distance between the first end and the second end is shortened.

Abstract: A cable holding device for holding a cable, includes a first member, a second member and a fixing member. The first member has a first through hole through which the cable is to pass. The second member has a second through hole through which the cable is to pass. The fixing member fixes the second member to the first member in such a condition that the second through hole partially overlaps the first through hole to hold the cable by an inner periphery of the first through hole and an inner periphery of the second through hole.

Abstract: An electronic device includes a housing, frame, and a lock attachment mechanism. The housing includes a front cabinet, and back cabinet which has opening and is attached to the front cabinet. The frame is disposed in the inside of the housing. The lock attachment mechanism includes lock attachment portion and hook portion. The lock attachment portion includes a pull-out portion with a hole disposed therein, and a leg portion protruding from the pull-out portion. The hook portion includes fixing portions attached to frame, and grappling portions that hook the leg portion with the pull-out portion being pulled out, and that form a gap through which the pull-out portion can be pulled out. The device further includes back cabinet having a holder. The holder restricts a movable range of lock attachment portion and holds the leg portion such that lock attachment portion is disposed at a location which allows the pull-out portion to be pulled out through opening.
