Abstract
Disclosed is a high-pressure pump which can easily be installed in an internal-combustion engine. Specifically disclosed is a high-pressure pump 1 provided with a mounting member 100. The mounting member 100 is fixed to a pivot 70 so as to keep such an attitude of a rocker arm 60 that the protruding end part of the pivot 70 is positioned within a concave 65a formed on a second end 65 of the rocker arm 60 and that the outer circumferential surface of the protruding end part of the pivot 70 is apart from the inner circumferential surface of the concave 65a by coming in contact with an arm body 62 of the rocker arm 60 to resist a turn of the rocker arm 60 around a roller 61 under the weight thereof, before a plunger 50 is brought into contact with a first end 64 of the rocker arm 60, and so as to come out of contact with the arm body 62 when the rocker arm 60 turns in reverse to the turn under the weight thereof, after the plunger 50 is brought into contact with the first end 64.
