The invention provides a power transmission device, a transmission device, and a fixing structure. The power transmission device can achieve a simplified structure. When the hydraulic oil does not flow into the oil passages (38, 62), the pressing member (41) is biased toward the parking brake (28) by the elastic force of the spring (43), and the acting portion (42) of the pressing member (41) presses the clutch plate (27). As a result, the clutch disc (25) and the clutch plate (27) are pressed against each other, the parking brake (28) is engaged, and the first shaft (11) is braked. In addition, the pressing force is transmitted to the double-shaft coupling clutch (33) via the common member (21), and the clutch plate (31) and the clutch disc (32) are pressed against each other. As a result, the double-shaft coupling clutch (33) engages, and the first shaft (11) and the second shaft (12) are coupled. 本发明提供一种动力传递装置、变速装置及固定结构。所述动力传递装置可以实现结构的简化的动力传递装置。在工作油没有流入油路(38、62)的状态下，利用弹簧(43)的弹性力，按压部件(41)向停车制动器(28)侧被施力，按压部件
