To easily manufacture and improve strength by forming a sampling blade body by plastic-forming a cup blade and a lever in one body and by bonding both sidewalls of the lever by welding or an adhesive agent.
Sampling blade bodies 6, 7 are constituted of a cup blade 10 and an interlocking lever 11, and are openably assembled to a holder by an open/shut link mechanism. These sampling blade bodies 6, 7 form the cup blade 10 and the interlocking lever 11 in one body by press working. A sampling recess section 18 opening a sampling mouth section 18a at a round peripheral wall 19 is formed in the cup blade 10. The interlocking lever 11 is formed by overlapping sidewalls 20, 21 with each other. A proximal end 20a of the sidewall 20 and distal end 19a of one end of the peripheral wall 19 of the cup blade 10 are formed in one body. A proximal end 21a of the sidewall 21 and a distal end 19b of the other end of the peripheral wall 19 are formed in one body. Both sidewalls 20, 21 of the interlocking lever 11 are welded at a welding section 24 to be bonded together. Easy manufacture can be realized.
