The present invention provides a solvent-free varnish composition, including: a thermosetting resin (A) having two or more (meth)acryloyl groups in a molecule thereof; a thermosetting resin (B) having one or more epoxy groups in a molecule thereof; a monofunctional vinyl-based monomer having an ether bond or an ester bond; an organic peroxide having a 10-hour half-life temperature of 40&#xb0; C. or more; and a curing catalyst for an epoxy resin, in which a mixed resin of the thermosetting resin (A) and the thermosetting resin (B) has an epoxy equivalent of from 500 to 5,000. The solvent-free varnish composition can be used as an insulating varnish that shows a small energy loss and requires a short curing time in its curing treatment step, and that provides a cured product that barely causes the precipitation of an oligomer or the like even when exposed to a refrigerant-based environment containing a refrigerant and a refrigerating machine oil under high temperature and high pressure.

An object is to provide a vent plug having a structure in which an air-permeable membrane is unlikely to be damaged. More specifically, a vent plug is produced, which includes: a cylindrical memberhaving a through-hole; a supportconnected to the cylindrical memberso as to be across the through-hole; and an air-permeable membranecircumferentially attached to the cylindrical member, wherein the air-permeable membraneis held on the supportand a convex portionthat follows the shape of the supportis formed on the air-permeable membrane

Vent plug

An object is to provide a vent plug making liquid unlikely to accumulate therein, while preventing an air-permeable membrane from breaking by means of at least one convex part. The vent plug of the present invention includes a cylindrical memberhaving a through-hole, and an air-permeable membraneattached around the cylindrical member, wherein the air-permeable membranehas a circumferential attachment region which is in contact with the cylindrical member, and an air-permeable region facing the through-hole, the cylindrical memberis provided with at least one convex partwhich projects beyond the plane including the air-permeable region, and the circumferential attachment region of the air-permeable membranehas a shape following a part or the entire of the convex part

A fishing reel includes: a reel body attachable to a fishing rod; a spool rotatably supported by the reel body; a handle disposed at a side portion of the reel body for rotating the spool to winding a fishing line on the spool; and an auxiliary operating member for auxiliary winding the fishing line on the spool provided at a position in which the auxiliary operating member can be operated by a finger of an angler's hand holding the fishing rod to which the reel body is attached.

Fishing reel

An electric fishing reel which is provided with a speed change mechanism excellent in silence and durability while realizing the size reduction. The electric fishing reel comprises: a drive motor for rotationally driving a spool rotatably supported on a reel body; a speed change mechanism rotatably mounted on a motor spindle and including an output gear having a rotational speed switched into a high speed or a low speed in accordance with the rotational direction of the motor spindle; and a power transmission mechanism for transmitting the rotation of the output gear to the spool. The speed change mechanism switches the rotational speed of the output gear by regulating the transmission of the rotation of the motor spindle with respect to the output gear.

The present invention provides a rotor for a rotary electric machine that suppresses the occurrence of winding disturbances in the process of winding a coil wire and has a coil field having a uniform outside diameter that is less likely to collapse. A coil field of a rotor coil is constructed by winding a coil wire having a circular cross section onto an outer circumference of a drum portion of a bobbin in multiple layers so as to make columns in each of the layers equal in number in an axial direction. Odd numbered layers of the coil field are constructed such that the coil wire is wound for approximately one turn around the drum portion in contact with an inner peripheral wall surface of a first flange portion of the bobbin, then wound into a plurality of columns in an axial direction such that the columns of the coil wire contact each other, and the coil wire in a final column forms a gap S relative to an inner peripheral wall surface of a second flange portion of the bobbin, and even numbered layers of the coil field are constructed such that the coil wire is wound for approximately one turn around the drum portion in contact with an inner peripheral wall surface of the second flange portion, then wound into a plurality of columns in an axial direction such that the columns of the coil wire contact each other, and the coil wire in a final column forms a gap S relative to an inner peripheral wall surface of the first flange portion. The gap S satisfies an expression D/4&#x2266;S&#x2266;D/2 relative to a diameter D of the coil wire. Thus, because the occurrence of winding disturbances in the process of winding the coil wire is suppressed, the coil wire can be wound into an aligned state, enabling a coil field that is less likely to collapse to be achieved, and the outside diameter of the coil field is made uniform, also preventing damage to an electrically-insulating coating resulting from contact with claw-shaped magnetic poles.
