  • Patent number: 10054126
    Abstract: A casing includes a first plate made of a metal, a support made of a resin, and a second plate fixed to the support. The first plate includes a flat plate portion, a through hole passing through the flat plate portion, and a claw portion extending upward from an edge of the through hole. A portion of the support is located in the through hole. The support covers a portion of the claw portion such that the support is prevented from turning and from coming off in an upward direction. The claw portion is defined by a portion of the first plate extending along a longest line segment inside the through hole in a plan view being bent upward from the flat plate portion. This enables the claw portion to have a great length even in a small area of the first plate to securely fix the support to the first plate.
