PROBLEM TO BE SOLVED: To provide a drum type shift device capable of attaining simplification and downsizing of a structure for making a parking state appear.SOLUTION: A drum type shift device comprises: a parking actuation arm including an engaging part that can be engaged with a parking uneven part of a parking member, and being capable of taking a parking position where the engaging part is engaged with the parking uneven part around an oscillation axis and the parking member is forcibly brought into rotation stop state; a parking cancel spring which energizes the parking actuation arm in a parking cancel direction around the oscillation axis; and a parking push member including a main body part which is supported by the drum member, and a cam push part which extends radially outwards from the main body part. The cam push part pushes the parking actuation arm towards the parking position against an energizing force of the parking cancel spring in response to a rotating operation of the drum member to the parking position.SELECTED DRAWING: Figure 13

    【課題】パーキング状態を現出させる為の構造の簡略化及び小型化を図り得るドラム型変速装置を提供する。【解決手段】本発明は、パーキング部材のパーキング用凹凸部に係合可能な係合部を有し揺動軸線回りに前記係合部が前記パーキング用凹凸部に係合して前記パーキング部材を強制的に回転停止状態とさせるパーキング位置を取り得るパーキング用作動アームと、揺動軸線回りパーキング解除方向へ前記パーキング用作動アームを付勢するパーキング解除バネと、前記ドラム部材に支持された本体部及び前記本体部から径方向外方へ延在されたカム押動部を有するパーキング用押動部材とを備え、前記カム押動部は、ドラム部材のパーキング位置への回転動作に応じて前記パーキング解除バネの付勢力に抗して前記パーキング用作動アームをパーキング位置へ向けて押動する。【選択図】図13
