Engine cooling device

An engine cooling device (100) includes: a water pump; a radiator (2); a first cooling water channel (8a) going through the radiator (2); a second cooling water channel (8b) not going through the radiator (2); a solenoid valve (6) provided in the second cooling water channel (8b); and a control unit (7). The control unit (7) moves, at a time of closing the solenoid valve (6), a valve body (62) in a valve closing direction while the cooling water is passing at a decreased flow rate so as to close the solenoid valve (6) to cut off passage of the cooling water in the second cooling water channel (8b). 发动机冷却装置(100)包括：水泵；散热器(2)；第1冷却水流路(8a)，其经过上述散热器(2)；第2冷却水流路(8b)，其不经过上述散热器(2)；电磁阀(6)，其设于上述第2冷却水流路(8b)；以及控制部(7)。上述控制部(7)进行如下控制：在使上述电磁阀(6)关闭时，在使流量减小后的上述冷却水流通的状态下使上述阀体(62)向关闭方向移动，由此使上述电磁阀(6)关闭来切断上述第2冷却水流路(8b)中的上述冷却水的流通。
