Title: VARIABLE FLOWRATE VALVE MECHANISM AND SUPERCHARGER
Abstract:
This variable flowrate valve mechanism, which opens and closes an opening part of a variable gas flowrate passage, is provided with: a valve body that opens and closes the opening part; a stem that passes through a housing and is supported so as to be capable of rotating relative to the housing, the valve body being linked to one end of the stem; an operating rod that is connected to an actuator and moves in a reciprocating manner; a link member that extends in a direction intersecting the stem and the operating rod and swings about the axis of the stem, one end of the link member being linked to the stem, and the other end of the link member being linked to the operating rod; and an urging member that is linked to a pair of linking parts disposed at both ends of the link member in the direction in which the operating rod moves in a reciprocating manner, the urging member curving so as to protrude to the longitudinally outer side of the link member and urging the link member in the longitudinal direction of the link member.
