PROBLEM TO BE SOLVED: To provide a knock type applicator capable of making operational feeling furthermore lighter while preventing a loss of a knocking force when a highly viscous content is delivered, reducing the number of parts, and making the manufacturing easy.SOLUTION: When a delivering body 20 is forwarded by a knocking operation, the forwarding operation is converted into a rotational operation in one direction of a transmitting cam body 18 by a guide channel 20a and a projecting part 18b of the delivering body, and a cam 18a of the transmitting cam body 18 is engaged with the cam 16b at the back of the rotational cam body 16, and the rotational cam body 16 is rotated by the rotation of the transmitting cam body 18 to forward the piston 12 by forwarding the screw shaft 14. On the other hand, by releasing the knocking operation, the delivering body 20 is retreated by an elastically recovering force of a spring 18c, and the retreating operation is converted to a rotational operation in the other direction of the transmitting cam body 18 by the guide channel 20a and the projecting part 18b to be returned to an original position, and operations of the rotational cam body 16 and the piston 12 are regulated. |
