PROBLEM TO BE SOLVED: To provide a sample collection device capable of collecting samples located at plural positions different in radial direction with respect to a rotation shaft.SOLUTION: The sample collection device includes: a rotation shaft 23 which is inserted and rotated in an uncured improvement body; holders 29, 30 each of which is integrally fixed to the bottom end part of the rotation shaft 23 and each of whose longitudinal direction protrudes to the outer circumferential side; molds 31 each of which has a cylindrical shape and is held in such a manner that an axial direction thereof becomes orthogonal to the longitudinal direction of the holder 29, 30; a stopper 28 provided protrudingly on the rotation shaft 23 so as to form a predetermined angle θ to the holders 29, 30 in the horizontal plane; a boss part 32 loosely fitted to the rotation shaft 23 so as to be rotatable; and lid plates 33, 34 whose base end parts are fixed to the boss part 32. The lid plates 33, 34 can take a closing position of closing end faces of the molds 31 and an opening position of opening the end faces of the molds 31 by coming into contact with the stopper 28.SELECTED DRAWING: Figure 2 |
