摘要： In an IPM rotor, a first core sheet has a first sheet hole forming a part of an accommodation hole. The first sheet hole has an edge portion having a flat spring portion which is bent by a magnet through insertion of the magnet into the accommodation hole. A pair of recesses forming a clearance with respect to the magnet are formed at both side portions of the flat spring portion of the edge portion of the first sheet hole. A size of the clearance is set based on a relationship between a magnitude of a pressing force of the flat spring portion on the magnet and variation in pressing force.

摘要： A common connecting section for connection to terminals at the same potential in circuits is placed outside a mold section to allow a reduction in size of a semiconductor module 1. Since the common connecting section is a portion of a lead frame which would be placed within such a mold section in a conventional semiconductor module, the mold section can be reduced in size as compared with the conventional one, thereby reducing the amount of mold resin and the material cost.

摘要： In this vehicle electronic control device, a control board having an electronic component mounted thereon is housed inside a case and a connector portion for connecting the control board to the outside is formed integrally with the case. The connector portion is formed by a housing portion covering the control board, and a terminal portion integrally embedded in the housing portion. The terminal portion has: a terminal for external connection, protruding from the housing portion; and an intermediate path portion extending from the terminal and connected to the control board. An exposure portion which allows the intermediate path portion to be exposed over the entire periphery thereof is formed in a part of the housing portion. An interface sealing member for sealing the interface between the housing portion and the intermediate path portion is provided in the exposure portion.
