Claims

[Scope of utility model registration request]

In an engine in which an output pulley is connected to one end of the crankshaft protruding from the crankcase, and an oil pump drive chamber is interposed between the pulley and the crankcase, a window hole is opened in one side wall of the drive chamber. A case forming one half of the drive chamber that communicates integrally through the window hole is formed so as not to come into contact with the pulley and is detachably attached in the radial direction of the crankshaft, and the case is provided with oil. A pump shaft is provided to protrude on the opposite side of the pulley in the direction of the crankshaft, and the oil pump shaft protrudes into the oil pump and the one half chamber, and the crankshaft and the oil pump shaft in the drive chamber and the one half chamber are provided. An oil pump mounting device characterized in that a power transmission member is disposed at each of the two members, and both members are connected through the window hole.
