To provide a click-type applicator, when delivering a high-viscosity content, with a lighter operational feeling while preventing the loss of clicking force and which can be easily manufactured with a reduced number of parts. In the click-type applicator, when the propelling element 20 is moved forwards by a clicking operation, the advancing motion is transformed into a rotary motion of a transfer cam element 18 in one direction by the function of guide slots 20a of the propelling element and projected parts 18b so that when a cam portion 18a of transfer cam element 18 meshes with a cam portion 16b at the rear of a rotary cam element 16, the rotation of the transfer cam element 18 causes rotary cam element 16 to rotate and thereby move the screw shaft 14 and hence a piston 12 forwards. On the other hand, by releasing the clicking operation, propelling element 20 is moved backwards due to the repulsive force of a spring 18c, and the backward motion is transformed into a rotary motion of transfer camelement 18 in the other direction by the function of the guide slots 20a and projected parts 18b so as to restore the original position, whereby operational actions of the rotary cam element 16 and piston 12 are restrained. |
