To provide a nail structure of shellfish taking shellfish efficiently scooping without damaging seashell at the bottom.SOLUTION: The nail structure of shellfish-removing jawlin of this invention protrudes forward and downward at the bottom side in the right and left direction of the scraping-side opening of cage 1, and shellfish inhabit with scraping progress of cage 1 A claw portion 12 which is inserted into the bottom layer portion and is composed of a large number of claw pieces curved in an arc shape in the traveling direction in which the shellfish is guided and housed in the cage 1, and the arcuate Right direction guide bar 16 for guiding the shellfish excavated from the bottom layer portion toward the outer peripheral side of the claw portion 12 when the scraping progresses is provided on the outer peripheral surface side. The guide bar 16 is mounted in the vicinity of an apex or a vertex in an arc shape in a side view.BACKGROUND OF THE INVENTION【課題】水底の貝を傷つけず効率良く掬い上げる貝取りジョレンの爪構造を提供する。【解決手段】この考案の貝取りジョレンの爪構造は、籠体1の掻取り側開口部の左右方向の底辺に前方下向きに突設され、籠体1の掻取り進行に伴い貝類が生息する底層部に挿入されて貝類を籠体1内に案内して収容させる進行方向に向って円弧状に湾曲した多数の爪片からなる爪部12を備えており、上記爪部12の円弧状の外周面側に掻取り進行時に底層部より掘起こされた貝を爪部12の上部外周側へ誘導させる左右方向のガイドバー16を設けている。ガイドバー16は側面視で円弧状の頂点又は頂点近傍に取付けられる。【選択図】図1
