Claims (1)

[Claims for Utility Model Registration] 1. A wiper motor device with a speed reducer, which has a clutch mechanism driven by a solenoid, and has a mechanism for eccentrically eccentricizing a crank output shaft and storing a wiper arm in a retracted position; It has a common terminal, a normally open park side terminal, and a normally closed travel side terminal, and detects that the crank output shaft is located at an intermittent stop position of the wiper arm by closing the common terminal and the park side terminal. A stop position switch, a wiper operation switch that selects wiper operation such as operation or stop, and a washer switch that can operate the washer motor and output a 1-bit washer signal indicating that the washer motor is in operation. , means for outputting a motor rotation signal in accordance with the washer signal, means for counting the number of times of wiping based on the signal from the stop position switch, and means for controlling the wiper arm to stop the wiper arm at a predetermined position after the number of times of wiping reaches a predetermined value. a control means using a microcomputer capable of outputting a rotation signal and a solenoid drive signal; a motor drive circuit that connects the wiper motor to a power source according to the motor rotation signal; and a connection between the solenoid and the power source according to the solenoid drive signal. A washer-linked wiper control device comprising: a solenoid drive circuit that enables the following; 2. A storage position switch that detects that the crank output shaft is located in the storage position of the wiper arm, and a storage cancel switch that selects not to perform the storage operation, and the wiper arm is configured to perform the retraction operation after the number of times of wiping reaches a predetermined value. The washer interlock according to claim 1 of the registered utility model claim, characterized in that the predetermined position at which the wiper arm is stopped has means for selecting either a retracted position or an intermittent stop position according to a signal from the retractable cancel switch. Wiper control device.
