≪１級課題 -機械工学-≫【問 1】[0002]
Pedestrians and drivers of vehicles traveling along roads areoften provided with visual indicators in the form of road surface markings,
which are white lines and so forth formed on road surfaces.
[0003]
Regarding such road surface markings, Patent Literature 1,for example, discloses a road surface marking paint including a synthetic
resin solution or liquid dispersion, and a filler. A road surface is coated withthe road surface marking paint, upon which a retroreflective material suchas glass beads or the like is dispensed, following which the paint is dried,
thereby forming a coating layer.
[0007]
With road surface markings formed by coating the roadsurface with road surface marking paint such as described in Patent
Literature 1 to 3, the coating layer of road surface marking paint is readily
lost due to friction from contact with pedestrians and vehicles. Accordingly,
maintenance needs to be periodically performed to recoat the road surface
with the retroreflective material (glass beads, etc.) and the road surface
marking paint, in order to maintain the road surface markings. Once
maintenance is started, lengthy traffic restrictions have to be imposed.
Accordingly, there has been demand for a technique for applying road surface
markings that requires less frequent maintenance.
[0008]
Now, it is conceivable to apply the road surface marking paintmore thickly at this time, so that the road surface markings are lost lessreadily from contact with pedestrians and vehicles. However, thickly
applying the road surface marking paint increases the force that the lower
side of the road surface markings in particular is subjected to from contact
with pedestrians and vehicles. Accordingly, the road surface markings easily
become detached from the road surface due to peeling away therefrom.

【問 2】[0014]
Now according to the present invention, in order to performbacklash adjustment in the geartrain of the reduction gear device 6
described above, the reference face 8b is provided in the gearbox 8, with theintermediate gear assembly 20 being disposed to be capable of sliding
displacement over this reference face 8b before fixation thereto, as describedabove. Also, later-described recesses 18 and 34 are bored in apices of theinput and intermediate shafts 14 and 26 of both the input gear assembly 10
and the intermediate gear assembly 20, along substantially axial centersthereof.
[0015]
Furthermore, a simple jig is used in order to perform backlash
adjustment in the geartrain in the present invention. This jig is formed as arestraining jig 50 that fixes and restrains a distance L between a center axial
line of the input shaft 14 of the input gear assembly 10 and a center axial
line of the intermediate shaft 26 of the intermediate gear assembly 20, andincludes a rod-like portion 52, and engaging pins 54 and 56 protruding fromboth ends of the rod-like portion 52, as illustrated in Figs. 2 to 4. The
restraining jig 50 is designed and fabricated such that the center-to-center
distance L of both engaging pins 54 and 56 on the rod-like portion 52 issubstantially equal to the sum of pitch circle radii of both gears, namely, theinput gear 16 and the first-stage gear 22 of the intermediate gear assembly
20. Engaging both engaging pins 54 and 56 of the restraining jig 50 with theaforementioned recesses 18 and 34 bored in the apices of the input andintermediate shafts 14 and 26 of both the above-described input gear
assembly 10 and intermediate gear assembly 20 enables the distance
between both gears 16 and 22 to be restrained. Obviously, similar restraining
effects can be achieved through a configuration in which pin-like protrusions
that are equivalent to both pins 54 and 56 of the restraining jig 50 areformed on the distal ends of the input shaft 14 and the intermediate shaft 26,
while recesses that are equivalent to the recesses 18 and 34 are provided atboth ends of the rod-like portion 52 of the restraining jig 50, as a matter ofcourse.
Translator’s note: “減速ギア装置１０” in paragraph [0014] probably should
be “減速ギア装置６”, and has been corrected accordingly.
