PROBLEM TO BE SOLVED: To provide a cat claw sharpener that is space-saving relative to a pillar, door, frame body, etc., and that can be firmly installed.SOLUTION: The cat claw sharpener is characterized in that it includes: a claw sharpener a proximal part which is installed at least in one end of the claw sharpener and a clamp mechanism which is connected to the proximal part to clamp a body to be clamped. The proximal part is equipped with a longitudinal adjustment hole which can adjust a gap between the claw sharpener and the clamp mechanism. The clamp mechanism is composed of: a holding part which forms between it and a fixing part a housing space through a connection part and which is arranged oppositely to the fixing part and a pressurizing means which is installed in the holding part, which is made capable of advancing and retreating toward the fixing part, and which clamps the body to be clamped between the pressurizing means and the fixing part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 柱、扉、枠体等に対して省スペースで強固に設置することができる猫用爪とぎ器を提供する。【解決手段】爪とぎ具と、前記爪とぎ具の少なくとも一端部に設置される基部と、前記基部に連結され、被挟持体を挟持するクランプ機構とを備えることを特徴とする猫用爪とぎ器であって、基部は、前記爪とぎ具と前記クランプ機構との間隙を調整可能とする前後調整孔を備え、前記クランプ機構は、固定部との間に連結部を介して収容空間を形成し、前記固定部に対向配置される保持部と、前記保持部に設置されて前記固定部に向けて進退可能とし、前記固定部との間で前記被挟持体を挟持する押圧手段とを備える猫用爪とぎ器。【選択図】 図1
