Zusammenfassung

PROBLEM TO BE SOLVED: To provide a waste gate valve device of a turbocharger which can suppress that wobbling becomes large when the settling of an elastic member occurs while suppressing a constriction on a layout of the elastic member by widening an interval at a portion for installing the elastic member.

SOLUTION: This waste gate valve device comprises a disc spring 40 which is sandwiched between a waste gate side link arm 13 and a drive rod 30, and energizes the drive rod 30 to an extension direction of a center axis of a waste gate side connecting pin 14. Then, in the waste gate valve device, a protrusion 61 protruding toward the waste gate side link arm 13 is formed in a position near the waste gate side connecting pin 14 rather than the disc spring 40 at the drive rod 30.

【課題】弾性部材を設置する部分における間隔を広くして弾性部材の設計に制約が生じてしまうことを抑制しつつ、弾性部材がへたった場合にがたつきが大きくなってしまうことも抑制することができるターボチャージャのウェイストゲートバルブ装置を提供する。
【解決手段】このウェイストゲートバルブ装置は、ウェイストゲート側リンクアーム13と駆動ロッド30との間に挟み込まれていて駆動ロッド30をウェイストゲート側連結ピン14の中心軸の延伸方向に付勢する皿バネ40を備えている。そして、このウェイストゲートバルブ装置には、駆動ロッド30における、皿バネ40よりもウェイストゲート側連結ピン14に近い位置に、ウェイストゲート側リンクアーム13に向かって突出している凸部61が設けられている。
