Zusammenfassung:	To provide a rear wheel brake device for motorcycle that can reduce rear wheel-side unsprung weight and the number of components of a shaft drive type motorcycle.SOLUTION: In a rear wheel brake device for motorcycle that transmits driving force of a power unit (P) of a motorcycle (1) to a rear wheel (WR) through a drive shaft (45) extending in a vehicle body front-rear direction, the drive shaft (45) includes a propeller shaft (46) coupled to a rear end of an output shaft (42), protruding from a case member (34) of the power unit (P) to a vehicle body rear side, through a universal joint (43). The output shaft (42) is fitted with a brake disk (40) braked by a rear-wheel brake caliper (41). The rear wheel brake caliper (41) is fixed to a bracket (50) provided to a case member (34), and also arranged on a vehicle body upper side of the brake disk (40).SELECTED DRAWING: Figure 3 【課題】シャフトドライブ式の自動二輪車の後輪側のバネ下重量および部品点数を低減できる自動二輪車の後輪制動装置を提供する。【解決手段】自動二輪車（１）のパワーユニット（Ｐ）の駆動力を、車体前後方向に延びるドライブシャフト（４５）を介して後輪（ＷＲ）に伝達する自動二輪車の後輪制動装置において、ドライブシャフト（４５）が、パワーユニット（Ｐ）のケース部材（３４）から車体後方側に突出する出力軸（４２）の後端部にユニバーサルジョイント（４３）を介して連結されるプロペラシャフト（４６）を含む。出力軸（４２）に、後輪ブレーキキャリパ（４１）によって制動されるブレーキディスク（４０）が取り付ける。後輪ブレーキキャリパ（４１）を、ケース部材（３４）に設けられたブラケット（５０）に固定すると共に、ブレーキディスク（４０）の車体上方側に配設する。【選択図】図３
