PROBLEM TO BE SOLVED: To provide a shouldering manual sprayer enabling drive of a pump without trouble.;SOLUTION: The shouldering manual sprayer 100 includes a tank 1 holding a liquid and carried on the back of a worker, a pump 2 attached to the tank 1 and transferring the liquid held in the tank 1 under pressure, and a lever 3 rotatably attached to the tank 1. The pump 2 has a holding part 4 to receive the liquid from the tank 1 and a pressurizing part vertically reciprocating in the holding part 4 by rotating the lever 3 to vary the inner pressure of the holding part 4. The holding part 4 contains an upper vessel 6 and a lower vessel 7. The error of a relative position between a rotation shaft 3a and the holding part 4 can be lowered while keeping the sealing performance of the holding part 4 by providing the lower vessel 7 with both of a bearing 14 passing the rotation shaft 3a of the lever 3 and the fixing part P fixed to the tank 1.;COPYRIGHT: (C)2013,JPO&INPIT
