摘要： PROBLEM TO BE SOLVED: To fix a scale plate showing appearance amount of an inner member to an outer cylinder member of a spring system tension balancer to a position to be easily seen, corresponding to a fixing environment. SOLUTION: A tension balancer is so constituted that a coil spring is energized to pull back an inner cylinder protruding from a casing. An appearance amount indicating apparatus 10 fixed to the outside end portion of the inner cylinder 4 consists of a fixing ring 11, a bracket 12 and a scale plate 13. The fixing ring 11 is fitted to a protruding end portion of the inner cylinder 4 and fixed with fixing bolts 11b. On the fixing ring 11, the bracket 12 is fitted, the position of the bracket 12 to the fixing ring 11 is adjusted, and a pin 12a is made to be aligned with a recessed part 11d of the fixing ring 11 and fixed. The recessed part 11d is suitably selected, and the position of the bracket 12 around the shaft to the fixing ring 11 can be changed, so that the scale plate 13 is arranged at a position capable of visual observation.

摘要： PROBLEM TO BE SOLVED: To obtain a display panel device whose structure is simplified, whose operability is enhanced in both the manufacture and the assembly of a component and in which there is no fear that the graduation face of a display panel is worn out by a method wherein a bolt performs both an action to fix a flanged ring to a core cylinder and an action to prevent an arm plate from being pulled out. SOLUTION: A flanged ring 8 is fitted to the end part of a core cylinder 3, and an arm plate 10 which is composed of a circular hole part and of a display-panel detention part is prepared separately. The circular hole part is formed to be freely rotatable with reference to the ring 8, and it is brought into contact with a flange. A bolt 9 is screwed so as to leave a proper gap on the opposite side, and the ring 8 is fixed to the core cylinder 3. The arm plate 10 is not pulled out to the direction of an axial line thanks to the head of the bolt, it is freely rotatable with reference to the ring 8, and it always maintains a hung-down position.

摘要： PROBLEM TO BE SOLVED: To improve a trolley-wire-stopping tension balancer to allow an operator therebelow to read easily changes in length of a trolley wire due to atmospheric temperature changes, although they can be numerically read, using an attached slender line measure situated at high place. SOLUTION: A line measure 1c is marked on the side surface of a casing 1. A rod 2 is made to move into and out of the casing by the expansion and contraction of a trolley wire, and a hanging shaft 7 which moves along with the rod but does not rotate is mounted at the end of the rod, so that the rod 2 is moved along the line measure by means of a slider 8 horizontally secured to the lower end of the hanging shaft 7. Because the line measure uses the side surface, its design and the size of letters can be chosen freely for increased visibility.

摘要： PROBLEM TO BE SOLVED: To reduce the weight of a spring device, which is added to the trolley wire anchoring force, and to prevent the hindrance of the appearance by suspending a set of spring device into a cylindrical pillar used for anchoring a trolley wire. SOLUTION: A cylindrical pillar 1 supports a chain pulley 2 freely to be rotated with a horizontal shaft provided in a top thereof, and the cylindrical pillar 1 is provided with an annular inner edge 1a in a lower part thereof. A suspended cylinder 5 is freely elevated in the cylindrical pillar 1, and provided with an outer edge 5a in a lower end thereof so as to be engaged with the inner edge 1a of the cylindrical pillar 1 through a spring 4. When a trolley wire is moved in two ways by the sliding friction of a pantograph and temperature change, the suspended cylinder 5 is elevated inside of the cylindrical pillar 1 through a chain in response to the movement of the trolley wire, and finally, the suspended cylinder 5 is anchored by the inner edge 1a inside of the cylindrical pillar 1, and during this time, the tensile force is automatically adjusted by the spring 4. On the other hand, since a guide bar 7 is fixed to the cylindrical pillar 1 by a core through a fitting plate 7a provided in the lower end of the guide bar 7, posture of the suspended cylinder 5 is vertically held.
