Reactor

1. A reactor cooled by a cooler, the reactor comprising:

a heat dissipation sheet; and

a main body including:

a first coil and a second coil arranged in parallel to each other, a first bottom surface as a bottom surface of the first coil and a second bottom surface as a bottom surface of the second coil being aligned in a same plane, and the first bottom surface and the second bottom surface being configured to be pressed against an upper surface of the cooler via the heat dissipation sheet;

a resin cover that covers side surfaces and upper surfaces of the first coil and the second coil other than vicinity of the first bottom surface and the second bottom surface, the resin cover having a central section that covers the side surfaces of the first coil and the second coil between the first coil and the second coil; and

a pressing frame extending along outer peripheries of the first bottom surface and the second bottom surface, the pressing frame being configured to press the heat dissipation sheet toward the cooler, the pressing frame having a coupled section, the coupled section being coupled to a lower surface of the central section, and the pressing frame being able to be displaced in a vertical direction with respect to the resin cover other than the central section.

2. The reactor according to claim 1 , wherein

the pressing frame that is separately located from the central section is not in contact with the resin cover.

3. The reactor according to claim 1 , wherein

the first bottom surface and the second bottom surface are in contact with the heat dissipation sheet.

4. The reactor according to claim 1 , wherein

the pressing frame has such a shape that a first square for surrounding a first opening and a second square for surrounding a second opening share one side with each other,

the coupled section is arranged on a shared one side of the pressing frame.
