To provide a cooling structure of a brake caliper capable of efficiently cooling a brake caliper of a rear wheel with a simple structure.SOLUTION: The cooling structure of brake caliper, applied to a saddle-riding type vehicle (1) having a rear brake caliper (36) giving a braking force to a rear wheel (WR) and a swing arm (23) pivotally supporting the rear wheel (WR) rotatably, includes an air guide duct (60) fitted to a lower surface (23a) of the swing arm (23). On the air guide duct (60), in a side view of a vehicle body, an intake port (62) positioned at a vehicle body front part of the rear wheel (WR) and an exhaust port (67) disposed near the rear brake caliper (36), are provided. The intake port (62) of the air guide ducts (60, 160), in a front view of the vehicle body, is positioned outside a cowling (21) covering the side face of an engine (E). An inclined surface (63a) is formed at an outside lower part of the air guide duct (60) in a vehicle width direction.SELECTED DRAWING: Figure 4

    【課題】簡単な構造によって後輪のブレーキキャリパを効率よく冷却することができるブレーキキャリパの冷却構造を提供する。【解決手段】後輪(WR)に制動力を与えるリヤブレーキキャリパ(36)と、前記後輪(WR)を回転可能に軸支するスイングアーム(23)とを備える鞍乗型車両(1)に適用されるブレーキキャリパの冷却構造において、スイングアーム(23)の下面(23a)に取り付けられる導風ダクト(60)を備える。導風ダクト(60)に、車体側面視で、前記後輪(WR)の車体前方に位置する吸気口(62)と、リヤブレーキキャリパ(36)の近傍に配設される排気口(67)とを設ける。導風ダクト(60,160)の吸気口(62)は、車体正面視で、エンジン(E)の側面を覆うカウリング(21)の外側に位置する。導風ダクト(60)の車幅方向外側下部に傾斜面(63a)を形成する。【選択図】図4
