Further, the provision of the heat insulating portion 61 in a thin plate shape also facilitates the provision of the heat insulating portion 61 in a curved shape so that the heat insulating portion 61 covers the outside of the driver 50. Further, by providing the heat insulating portion 61 and the mounting portion 62 separately, the mounting structure of the mounting portion 62 and the housing 10 does not interfere with the heat insulating portion 61 and the driver 50 and the flat cable 40.
