Claims

[Scope of Claim for Utility Model Registration] A mounting bracket that is fixed to the engine body and used to detachably attach the oil filter to the engine body; The engine body has a recess formed in a portion where the mounting bracket is attached, and an oil intake passage whose tip opens into the recess and takes in oil purified by an oil filter. , a female threaded part into which the male threaded part of the mounting bolt is screwed into the open end of the oil intake passage; and an oil takeout passage whose front end opens into the recess and takes out dirty oil from the engine side. The mounting bracket is coaxial with the oil intake passage, and has a mounting hole through which the mounting bolt is inserted, and communicates with this mounting hole from the side, through which oil purified by the oil filter flows out. and an oil outflow passage, the mounting bolt passes through the mounting hole, and the male threaded portion is screwed into the female threaded portion of the oil intake passage to secure the mounting bracket to the engine body. An engine characterized in that a communication passage for communicating an outflow passage and an oil intake passage with each other is provided in a state penetrating the inside, and the inside of the recess and the oil outflow passage are separated from each other in a liquid-tight manner by a sealing member. Oil filter mounting structure.
