Electronic device e.g. sensor, mounting and indexing device, has nose shaped protrusion engaging with counter-nose formed by extension at one end of electronic device case having unit to retain another case end in groove of support

摘要

The device has a position indexing part with a protrusion (4) in the form of nose extending in an inclined manner towards the bottom of a groove of a support at a mounting state. A case (2) of an electronic device has, at its one end, an extension (5) constituting counter-nose to engage with the nose to lock the case in a mounted position.
