  • Patent number: 11324207
    Abstract: A dual-bearing reel configured to feed a fishing line forward is disclosed. The dual-bearing reel includes a reel body and a handle. The reel body has a first side plate, a second side plate, and a connecting portion. The first side plate includes a circular portion having a circular shape, and a bulging portion bulging forward and downward from the circular portion. The second side plate is circular and disposed apart from the first side plate. The connecting portion connects the first side plate and the second side plate. The handle is rotatably mounted on the first side plate. A first central axis of the circular portion of the first side plate is offset forward and downward from a second central axis of the second side plate.

  • Patent number: 10765097
    Abstract: A dual-bearing reel includes a reel body, a spool, a handle, and a spool shaft. The reel body has a first side plate having a first opening that opens in an axial direction of the spool shaft and through which the spool can pass, a second side plate that faces the first side plate, and a second side cover that is mounted on the second side plate. The spool has a bobbin trunk and a second flange. The handle is rotatably provided on the first side plate side of the reel body. The second side plate has a second opening that opens in the axial direction and a fixing portion for mounting a second side cover member, the fixing portion being provided on a peripheral edge of the second opening and at a position overlapping the second flange as viewed in the axial direction.

  • Patent number: 6096692
    Abstract: The present invention relates to a synthetic lubricating oil comprising cyclic ketals or cyclic acetals obtained by a reaction between one or more polyhydric alcohols having an even number of hydroxyl groups of not less than 4 and not more than 10 and one or more specific carbonyl compounds, or one or more ketals or acetals which are reactive derivatives of said carbonyl compounds; a working fluid composition for a refrigerating machine comprising a hydrofluorocarbon and a refrigeration oil containing the cyclic ketals or cyclic acetals; and novel compounds of the above cyclic acetals and a production method thereof. The present invention provides a synthetic lubricating oil which shows a good thermal stability, a good oxidation resistance, no carboxylic acid formation due to hydrolysis and a low hygroscopicity and is inexpensive as well.
