To improve reliability of a parking lock mechanism in a drum type transmission.SOLUTION: A parking lock mechanism 500 of a drum type transmission has: a parking gear 110L provided on a transmission shaft 810; a parking operating arm 510 that can be displaced to a lock position of engaging with the parking gear 110L and an unlock position of separating from the parking gear 110L; a pushing member 530 for parking that pushes the operating arm 510 to the lock position in response to the rotational movement of a drum member 140 from a shift position or a neutral position to a parking position. When the drum member 140 is at the parking position, a parking lock holding mechanism 700 engages a gear lock member 702 with a lock member engaging part 204a provided on any gear 204 of a plurality of shift gears constituting a shift gear row 200, to prohibit the rotation of the shift gear 204.SELECTED DRAWING: Figure 6

    【課題】ドラム型変速装置におけるパーキングロック機構の信頼性を向上する。【解決手段】ドラム型変速装置のパーキングロック機構500は、変速軸810に設けたパーキングギヤ110Lと、パーキングギヤ110Lに係合するロック位置とパーキングギヤ110Lから離れるロック解除位置とに変位自在なパーキング用作動アーム510と、ドラム部材140の変速位置又は中立位置からパーキング位置への回転動作に応じて作動アーム510を押動してロック位置にするパーキング用押動部材530を有し、パーキングロック保持機構700は、ドラム部材140がパーキング位置にあるときに、シフトギヤ列200を構成する複数のシフトギヤのうちいずれかのギヤ204に設けたロック部材係合部204aにギヤロック部材702を係合して該シフトギヤ204の回転を禁止する。【選択図】図6
