`
`AMENDMENT TO THE CLAIMS
`
`This listing of claims will replace all prior versions, and listings, of claims in the
`
`application:
`
`1.(Currently Amended) A « toothforbuckets,comprising:
`
`a loath pointsouphng-tareet-obiect having a coupling space that comprisesa first space
`
`and a second space communicating with each other;
`
`a damperstructure accommodatedin the first space, and comprising a flexible portion
`
`having an insertion groove which is positioned on one surface of i
`of and a hollow therein
`
`
`
`extendingfromtheonesurfacetoanothersurfaceoppositetotheonesurfaceandhavingone
`
`side which is open, -anda hard portion inserted in the Insertion sroove eoupled-te-theexible
`
`
`
`porties-and having one surface whichisaflatsurfaceand isexposedto an outside,andasealing
`
`portion blocking the opened side of the hollow; and
`
`
`a coupling unit accommodated in the second space, a portion of which is in contact with
`
`sheone surface of the hard portion,
`
`
`wherein, in responseto rotation of the coupling unit in the second spaceframaninitial
`
`state, another portion different from the portion of the coupling unit comesinto contact with the
`
`hard portion,
`
`wherein when the coupling unit rotates in one direction from teasinitial state, i-which
`
` :8;to becomea first rotation state, a portion
`
`where the coupling unit and the hard portion contact each other is movedin a direction toward
`
`the flexible portion further than the initial state, and thus, the hard portion is moved in the
`
`direction toward the flexible portion further than the initial state, and
`
`wherein the flexible portion is compressed and deformed between the hard portion and an
`
`inner surface of the toothpointes st forming the first space;-.
`
`2. (Currently Amended)
`
`The ckets of claim 1,
`
`wherein the damperstructure comprises:
`
`a coupling surface coupled to the hard portion;
`
`
`
`Appl. No.: 17/396,113
`Reply to Office Action of June 14, 2023
`
`a support surface positioned on an opposite side of the coupling surface; and
`
`a connection surface connecting the coupling surface and the support surface,
`
`wherein the support surface and the connection surface are in contact with the inner
`
`surface of the toothporte sect formingthe first space.
`
`3. (Currently Amended)
`
`The retoathforbucketsof claim 2,
`
`wherein at least a part of an externally exposed portion of the coupling surface is in
`
`
`
`contact with the inner surface ofthe tooth pourte seet formingthe first space.
`
`4. (Currently Amended)
`
`The cambined-structuretocth for buckets of claim 1,
`
`wherein the flexible portion is in contact with the inner surface of the tgathpointseuphve
`
`target-obieet forming the first space.
`
`5. (Currently Amended)
`
`The eamiined-structursiogth for buckets of claim 1,
`
`wherein when the coupling unit further rotates in the one direction in thefirst rotation
`
`state to become a secondrotation state, the portion where the coupling unit and the hard portion
`
`contact each other is moved in a direction toward the coupling unit further than in the first
`
`rotation state, the hard portion is moved in a direction toward the coupling unit further than in the
`
`first rotation state, and thus,at least a part of the flexible portion is restored from being
`
`compressed and deformedin thefirst rotation state.
`
`
`
` 6. (Currently Amended) The cambined-structaretoothforbuckets of claim 1,
`
`wherein a shape ofthe flexible portion is deformed to reduce a volumeof the hollow, and
`
`wherein whenan external force applied to the hard portion is reduced byrotation of the
`
`coupling unit in a state in which *ss3 volumeofthe flexible portion is reduced,
`
`sss volume of
`
`the hollowis restored.
`
`7.(Canceled)
`
`8. (Currently Amended)
`
`The saminsed-structuretooth for buckets of claim 1,
`
`wherein the toothpointe ‘eet is a tooth point of an excavator, and
`
`
`
`Appl. No.: 17/396,113
`Reply to Office Action of June 14, 2023
`
`wherein the coupling unit couples the ‘eeticoth point to a tooth adapter.
