Installation structure for reservoir tank

Abstract

An installation structure for a reservoir tank includes a main frame that extends rearward from a head pipe, a down frame that extends downward from the head pipe, a bridge that connects the down frame and the main frame, a radiator disposed in front of the engine and configured to radiate heat from cooling water of an engine, and a reservoir tank configured to adjust a flow rate of cooling water in the radiator. The reservoir tank is provided above the engine and rearward of the radiator so as to overlap a region surrounded by the main frame, the down frame, and the bridge in a side view.

What is claimed is: 
     
         1 . An installation structure for a reservoir tank, the installation structure comprising:
 a main frame that extends rearward from a head pipe;   a down frame that extends downward from the head pipe;   a bridge that connects the down frame and the main frame;   a radiator disposed in front of the engine and configured to radiate heat from cooling water of an engine; and   a reservoir tank configured to adjust a flow rate of cooling water in the radiator,   wherein the reservoir tank is provided above the engine and rearward of the radiator so as to overlap a region surrounded by the main frame, the down frame, and the bridge in a side view.   
     
     
         2 . The installation structure for a reservoir tank according to  claim 1 ,
 wherein the radiator overlaps a fuel tank in a front view, and   the reservoir tank is provided between the radiator and the fuel tank.   
     
     
         3 . The installation structure for a reservoir tank according to  claim 1 ,
 wherein a part of the reservoir tank is inserted between the main frame and the bridge in a front view.   
     
     
         4 . The installation structure for a reservoir tank according to  claim 1 , further comprising
 a side cover covering the reservoir tank from a lateral side,   wherein an opening partially exposing the reservoir tank is formed in the side cover, and an inspection line for cooling water is formed on a tank side surface of the reservoir tank, and   wherein the opening of the side cover exposes a portion of the reservoir tank which is upper than the inspection line in the side view.   
     
     
         5 . The installation structure for a reservoir tank according to  claim 1 ,
 wherein a water supply pipe extends obliquely upward and forward from a tank upper portion of the reservoir tank, and   a water supply port disposed at a distal end of the water supply pipe is exposed to an upper side of the radiator in a front view.   
     
     
         6 . The installation structure for a reservoir tank according to  claim 5 ,
 wherein a water supply port is formed in an upper portion of the radiator, and   the water supply port of the water supply pipe of the reservoir tank is located between the water supply port of the radiator and the main frame in the front view.
