Abstract: A pulling detection device includes: a base in which, on a foundation portion, a first wall portion, a projection, and a second wall portion are provided; a movable rod including a switch operation body and a pulling rod, the switch operation body having a first wall portion opposed surface, a projection opposed surface, and a second wall portion opposed surface, the pulling rod extending from the second wall portion opposed surface, while movement of the movable rod toward one side is restricted by contact between the first wall portion and the first wall portion opposed surface and movement of the movable rod toward another side is restricted by contact between the projection and the projection opposed surface; an elastic body provided between the second wall portion opposed surface and the second wall portion; a first switch which operates by contact/separation; and a second switch which operates by contact/separation.

Abstract: This wedge looseness inspector for a rotary electric machine includes: an inspector including a wedge striker having a tap hammer for striking a wedge, and a wedge vibration detector for detecting vibration of the wedge; and attraction portions connected to the inspector via connection members and being attractable to an outer circumferential surface of a stepped-down portion, wherein the attraction portions have, on an inner side in the axial direction, first attachments that allow adjustment of the attached position in the axial direction of the attraction portions or replacement thereof.

Abstract: An endless-track traveling apparatus includes a casing, pulleys having axes arranged in parallel in the casing, a motor for driving the pulleys, and an endless track wound on outer circumferential surface portions of the pulleys to rotate together with the pulleys and move on a traveling target. The endless-track traveling apparatus further includes: a plate-shaped member disposed in contact with the endless track and opposed to the traveling target in a space surrounded by the endless track, and fitted in the casing; a magnet fixed in the casing to attract the traveling target; and an elastic member having one end in contact with an inside of the casing and another end in contact with the plate-shaped member, and urging the plate-shaped member in such a direction as to press the plate-shaped member against the endless track.
