Abstract
A variable flowrate valve mechanism includes: a valve body that opens and closes the opening portion; a stem of which one end is connected to the valve body and is supported so as to be rotatable relative to a housing; an operating rod that is connected to an actuator and reciprocates; a link member of which one end is connected to the stem and the other end is connected to the operating rod and which extends in a direction crossing the stem and the operating rod; and a biasing member that is connected to a pair of connecting units disposed on both sides of the link member in a direction where the operating rod reciprocates, is bent so as to protrude outward in a longitudinal direction of the link member, and presses the link member in the longitudinal direction of the link member.

A variable flowrate valve mechanism that opens and closes an opening portion of a variable gas-flow-rate passage, the variable flowrate valve mechanism comprising:
- a valve body that opens and closes the opening portion;
- a stem of which one end is connected to the valve body, passes through a housing, and is supported so as to be rotatable relative to the housing;
- an operating rod that is connected to an actuator and reciprocates;
- a link member of which one end is connected to the stem and the other end is connected to the operating rod and which extends in a direction crossing the stem and the operating rod and swings about an axis of the stem;
- and
- a biasing member that is connected to a pair of connecting units disposed on both sides of the link member in a direction where the operating rod reciprocates, is bent so as to protrude outward in a longitudinal direction of the link member, and presses the link member in the longitudinal direction of the link member.
