Abstract: A current sensor which suppresses deterioration of detection accuracy caused by high temperature of electronic components due to heat of a bus bar and is suitable for measurement of large current includes a bus bar through which a current to be measured flows, a magnetic detector detecting a magnetic field generated by the bus bar, and a case integrally formed with the bus bar and having a storage space storing the magnetic detector. The magnetic detector is spaced away from and faces the bus bar. The bus bar is on a first surface of the storage space defining the storage space and facing the magnetic detector. A low thermal conductivity material having a lower thermal conductivity than a resin-based material forming the case is provided between the bus bar and the magnetic detector to contact an opposing surface, on the bus bar, facing the magnetic detector.

Abstract: A door handle apparatus to be attached to a door of a vehicle is provided. The door handle apparatus includes a case, a strain body, and an elastic mechanism. The case includes an outer case provided so as to face a vehicle exterior side and an inner case provided so as to face a vehicle interior side. The outer case and the inner case are integrated with each other. The strain body is provided in the case, has a sensor mounted on a middle portion between one end portion and an opposite end portion of the strain body, and the one end portion of the strain body is fixed to a portion on a center side of the inner case. The elastic mechanism uses an elastic force to press the opposite end portion of the strain body against a fixing portion at an end of the inner case.

Abstract: A restricting device for a flexible wiring board includes an insertion portion into which at least both side portions of the flexible wiring board are inserted. The insertion portion includes: a rear restricting portions protruding in a thickness direction of the flexible wiring board; a front restricting portion located forward of the rear restricting portion in an insertion direction; a restricting region formed between the front restricting portion and the rear restricting portion, and an inner restricting portion located further inward than the rear restricting portion with respect to a width direction of the flexible wiring board and protruding in a direction opposite to a protruding direction of the rear restricting portion. The protruding portion passes over the rear restricting portion and is restricted from moving in a front-rear direction in the restricting region while the flexible wiring board is being inserted into the insertion portion.
