Guide structure for an electronic unit

摘要

A guide structure for an electronic unit in an electrical connection box is attached to a unit attaching surface while inserted along guide walls of an electrical connection box body. Guide grooves, each extending in an electronic unit insertion direction, are arranged at least on outer surfaces of confronting peripheral walls of the electronic unit, and guide ribs that are engageable with the guide grooves and that can position an electronic unit of different size are projectingly disposed on the unit attaching surface. The guide structure for the electronic unit can prevent oblique insertion of the electronic unit when the electronic unit is attached to the electrical connection box while inserted between guide walls of the electrical connection box. The guide structure also allows attachment of the electronic unit of different size.
