Patent number: 8075772Abstract: The present invention provides an oil pan with a built-in filtering element which does not easily receive influence of lateral swing of oil, which has high support rigidity of a filter, or which has excellent assembling operability of the filter, or which is light in weight as compared with a conventional oil pan. The oil pan P1 with a built-in filtering element has a filter 20. The filter 20 is provided therein with an oil flow path Q which is in communication with an oil pump. The filter 20 filters oil flowing toward the oil pump. An oil flow path includes a bottom flow path Qb having a flow path wall 7 extending along a bottom wall 5 of the oil pan, and a side flow path Qs having a flow path wall 8 extending along a first sidewall 1 of the oil pan. The first sidewall includes a drain hole 1h which opens at the bottom flow path and through which the filter can be inserted into the bottom flow path. The bottom flow path is provided with a filter retaining portion 7k which retains the inserted filter.Type: GrantFiled: March 30, 2006Date of Patent: December 13, 2011Assignee: Daikyonishikawa CorporationInventor: Takeharu Suga

Patent number: 7762419Abstract: A cap has a pair of L-shaped, flexible engaging arms that extend, from the end of a cap body opposite to the direction of fitting, in the direction of fitting with a distance away from the cap body. The distal ends of the engaging arms are connected by a pair of flexible connecting bridges to surround the outer periphery of the cap body with a distance away therefrom. The cap body is fitted into a cylindrical part of a cylinder head cover and engaging projections of the pair of engaging arms are engaged with an engaging recess in the outer periphery of the cylindrical part. The engaging arms are flexed to get away from the outer periphery of the cylindrical part by pushing circumferentially middle parts of the connecting bridges to come close to each other, so that the engaging projections are disengaged from the engaging recess.Type: GrantFiled: March 27, 2009Date of Patent: July 27, 2010Assignee: Daikyonishikawa CorporationInventor: Takeharu Suga
