Abstract:
1. A suction cap device capable of covering a liquid jetting surface, of a liquid jetting head, having a jetting port which is formed in the liquid jetting surface and through which a liquid is jetted, the suction cap device comprising: a cap member which is formed of an elastic member, which is configured to cover the liquid jetting surface, which is formed to have a recessed portion, and which has a suction port formed in a bottom surface of the cap member to be located inside the recessed portion; a suction mechanism which communicates with the suction port; and a cap protector which is accommodated in the recessed portion of the cap member, and which prevents, under a condition that the suction mechanism carries out a suction in a state that the liquid jetting surface is covered by the cap member, the cap member from being deformed due to decrease in pressure inside the recessed portion, the cap protector including a body and a liquid flow passage which has a lead-in port formed to penetrate through the body and open on a first surface, of the body, on a side opposite to the suction port and a lead-out port formed to penetrate through the body and open on a second surface, of the body, facing the suction port, and which causes the liquid inside the cap member to flow; wherein in the liquid flow passage, a diameter of the lead-in port is greater than a diameter of the lead-out port.
