Support structure for fuel injection valve

A support structure comprising an elastic support member for supporting a fuel injection valve on an engine, in which a nozzle part in a front end section of the fuel injection valve is fitted in an injection-valve mounting hole in the engine, and a fuel supply cap of a fuel distribution tube supported on the engine is fitted on a fuel introducing part in a rear end section of the fuel injection valve, the fuel injection valve having a first load receiving portion and a second load receiving portion along an axial direction thereof, the first load receiving portion being supported on the engine, and the second load receiving portion being supported on the elastic support member which receives a load from the fuel supply cap, wherein:

• the elastic support member includes a base plate configured to be placed on the second load receiving portion, and an elastic piece curving rearward from one end of the base plate and extending toward another end of the base plate, and having an apex portion thereof in pressure contact with a front end surface of the fuel supply cap,
• the base plate has an overhang portion overhanging from the second load receiving portion, the overhang portion abuttingly contacting and supporting a tip end portion of the elastic piece, the support structure configured such that the overhang portion is always kept in abutment against the tip end portion of the elastic piece, and
• a part of the base plate proximate the overhang portion is configured to start bending when a load the overhang portion receives from the fuel supply cap, through the elastic piece, reaches or exceeds a predetermined value.
