Description

  The present invention relates to an oil filter device, and more particularly to an oil filter device capable of downsizing a bracket and an engine and standardizing parts.

2. Description of the Related Art Conventionally, an oil filter device in which an oil filter is attached to a cylinder body of an engine via a bracket is known (see, for example, Patent Documents 1 to 4).
Patent Documents 1 to 4 disclose a structure in which a flange formed at a base end portion of a bracket is screwed to a cylinder body.

However, in the techniques of Patent Documents 1 to 4, a screw hole must be formed in the flange of the bracket, which increases the size of the flange and hinders downsizing of the engine. In addition, it is necessary to secure a space for using the tool for the work of screwing the flange, which also leads to an increase in the size of the flange and the engine.
Further, since the positions of the holes to be screwed differ depending on the shape of the engine, a bracket must be prepared separately for each engine, and the cost cannot be reduced by sharing the parts.
In the techniques of Patent Documents 1 to 4, generally, a gasket is provided between the flange of the bracket and the cylinder body to ensure liquid tightness. However, the bracket is tilted even slightly and the gasket floats. If the flange is tilted and attached, it becomes difficult to ensure liquid tightness. Further, there is a possibility that the oil path is displaced between the bracket and the cylinder body when screwing (for example, bolting a metal collar).
Furthermore, in the techniques of Patent Documents 1 to 4, since the oil passage of the bracket extends in a curved shape or a bent shape, the oil passage is complicated and the oil pressure loss increases.
