PROBLEM TO BE SOLVED: To provide a coolant spray device which cools a motor with a simple structure.SOLUTION: A coolant spray device includes: a nozzle 31 configured to jet a coolant; a motor 4 configured to adjust a rotation angle of the nozzle 31; a case 2 to which the nozzle 31 and the motor 4 are attached; and a heat sink 70 attached to an outer periphery of the motor 4 and exposed to the outside of the case 2. Since heat generated when the motor is operated is radiated from a portion of the motor exposed to the outside and the heat sink, the motor is cooled with a simple structure.SELECTED DRAWING: Figure 1 |
