a washer pump that feeds washer fluid under pressure to a jetting portion provided to at least one of the wiper blade or the wiper arm, to cause washer fluid to be jetted from the jetting portion toward the wiping surface on an outward movement direction side of the wiper blade during the to-and-fro wiping operation; and a control unit that, when a predetermined signal is detected, controls the wiper motor and the washer pump such that the to-and-fro wiping operation is performed, and such that washer fluid is jetted from the jetting portion toward the wiping surface on the outward movement direction side while a return path wiping operation of the to-and-fro wiping operation is being performed. ## Claims ### Claim 1 A vehicle wiper-washer device comprising: a wiper motor that causes to-and-fro wiping operation on a wiping surface by a wiper blade coupled to a wiper arm; a washer pump that feeds washer fluid under pressure to a jetting portion provided to at least one out of the wiper blade or the wiper arm, the washer pump causes washer fluid to be jetted from the jetting portion toward the wiping surface on an outward movement direction side of the wiper blade during the to-and-fro wiping operation; and a control unit that, in a case in which a predetermined signal has been detected, controls the wiper motor and the washer pump such that the to-and-fro wiping operation is performed, and such that washer fluid is jetted from the jetting portion toward the wiping surface on the outward movement direction side while a return path wiping operation of the to-and-fro wiping operation is being performed. ### Claim 2 (depends on 1) The vehicle wiper-washer device of claim 1, wherein the control unit further controls the wiper motor and the washer pump such that, after performing the to-and-fro wiping operation in which washer fluid is jetted from the jetting portion toward the wiping surface on the outward movement direction side while the return path wiping operation is being performed, jetting of washer fluid is stopped and the to-and-fro wiping operation is performed alone. ### Claim 3 (depends on 1) The vehicle wiper-washer device of claim 1, wherein the control unit further controls the wiper motor and the washer pump such that, in a case in which a predetermined signal has been detected, the to-and-fro wiping operation starts after starting to jet a predetermined amount of washer fluid toward the outward movement direction side, and such that washer fluid is jetted toward the outward movement direction side while performing the return path wiping operation of the to-and-fro wiping operation. ### Claim 4 (depends on 1) The vehicle wiper-washer device of claim 1, wherein the predetermined signal is a signal generated in at least one case out of a case in which a predetermined switch has been operated, or a case in which dirt has been detected by a detection section that detects the dirt on the wiping surface. ### Claim 5 (depends on 1) The vehicle wiper-washer device of claim 1, wherein, in a case in which travel is in progress, the control unit further controls the wiper motor and the washer pump such that a region where washer fluid is jetted on the outward movement direction side is limited to a predetermined region while the return path wiping operation is being performed. ### Claim 6 (depends on 3) The vehicle wiper-washer device of claim 3, wherein the control unit controls the washer pump such that a jetting amount of the predetermined amount of washer fluid jetted in a case in which the predetermined signal has been detected is a smaller amount of washer fluid jetted than a jetting amount of washer fluid first jetted in a case in which jetting of washer fluid has been instructed. ### Claim 7 (depends on 1) The vehicle wiper-washer device of claim 1, wherein the control unit controls the wiper motor and the washer pump such that, in a case in which the predetermined signal is continuously detected for a predetermined duration or longer due to a predetermined switch being continuously operated for a predetermined duration or longer, the to-and-fro wiping operation is performed, and an operation to jet washer fluid from the jetting portion toward the wiping surface on the outward movement direction side is repeated while performing the return path wiping operation of the to-and-fro wiping operation.
