Air intake device

Abstract

An air intake device includes: an air intake valve provided so as to change intake air by rotation of a rotation shaft; an actuator which is a driving source for rotating and driving the rotation shaft of the air intake valve; a first link member rotatable by a predetermined operation angle about the rotation shaft; a second link member rotatably connected to the first link member; a connection member which connects the first link member and the second link member so as to be rotatable to each other; and a biasing member whose one side end is engaged to the first link member and whose other side end is engaged to the second link member or the connection member to bias the first link member and the second link member or the connection member so that rattling between the first link member and the second link member is suppressed.
