Abstract: There is provided an oil separator for blowby gas exhibiting excellent oil separation performance in a stable manner. In a common flow path section of a gas flow passage in which the blowby gas flows and an oil passage provided with a bottom of the common flow path section where oil that has been separated from blowby gas by separation means provided midway along the gas flow passage, the width of a part of the common flow path section is regulated so as to become gradually smaller towards the bottom of the common flow path section, and a flow passage regulating section, for making part of the common flow path section that has the width regulated a restricted section, is provided so as to extend upwards from the bottom of the common flow path section.

Abstract: An antenna structure for vehicles capable of minimizing the distance between a first contact member and a signal processing circuit and ensuring stable antenna performance without using a connection line of a lengthy wire rod is provided. To realize this advantage, an antenna element is disposed on a rear window glass, and the first contact member is disposed at an end of the antenna element. Further, an amplifier case having an attachment flange facing the rear window glass is fixed to a roof panel, and the signal processing circuit is disposed in the amplifier case at a position sandwiching the attachment flange.
