Abstract:
An electronic control unit to be snap-fitted to a bracket, the electronic control unit comprising:a box-shaped case; and a circuit board on which electronic components are mounted, the circuit board being contained in the case, wherein the case comprises: a front opening from which the circuit board is inserted; a rear projection formed on a rear wall of the case, the rear projection being adapted to be snap-fitted to a resilient rear hook formed on the bracket; side projections formed on sidewalls of the case, the side projections being adapted to be snap-fitted to respective resilient side hooks formed on the bracket; and a guiding projection formed on at least one of the sidewalls, the guiding projection guiding the case to align the side projections with the resilient side hooks when the case is mounted on the bracket, wherein the guiding projection includes a sloped surface slidably contacting a corner portion of the resilient side hook to thereby rush the case toward the resilient rear hook against a resilient force thereof when the case is mounted on the bracket.
