Abstract: A reel seat comprises a seat main body that comprises a reel leg placing portion to which a reel leg is placed and fixed and a tubular portion provided with an opening hole into which a rear end portion of a rod is fitted and fixed, and a grip is disposed on a rear side of the reel leg placing portion. The opening hole is formed so the rod to be fitted and fixed is offset downward relative to an axial center X of the grip, is formed further on a lower side than the reel leg placing portion, and is formed so that a rear end edge of the rod is located further on a rear side than a front end of a reel leg in a state where the reel leg of a fishing reel is placed and fixed to the reel leg placing portion.

Abstract: In a reel seat of the present disclosure, a position of a reel leg placement portion on which a reel leg of a fishing reel is placed is offset in a descending direction with respect to a position of an axial center of a rod. An inclined surface connecting an upper end position of a hood portion defining an opening of a fixed hood to a grip upper surface gripped on the rear side of the fishing reel is provided on the rear side of the fishing reel attached to and fixed to the reel leg placement portion, and the inclined surface is formed such that an inclination angle ? of rising toward the grip upper surface from the upper end position of the hood portion does not exceed 45° and an inclination angle ? of descending from the grip upper surface does not exceed 35° in side view.

Abstract: A sound-reproducing device has a DSP and a ?Com performing a predetermined calculation to an input signal, and an AMP amplifying the calculated signal and outputting the signal to a speaker unit. The DSP and the ?Com cuts a part of a reverse characteristic of a frequency characteristic of the speaker unit in a low frequency, and superimposes the reverse characteristic on the input signal. The sound-reproducing device can overcome a shortage of low sound during reproduction of low to medium volume in the speaker unit having a relatively small diameter, and can keep reproduction sound quality without loss of the reproduction sound quality during reproduction of large volume.

Abstract: Where a super-elastic alloy is used as a core material, boundary separation can be prevented on substantial deflection. The super-elastic alloy is used as the core material, an outside layer made with fiber-reinforced resin is provided outside except the tip part region of the core material, and a resin-rich layer greater in resin ratio than the outside layer is provided between the outside layer and the core material so as to be adjacent to the core material.

Abstract: A battery holding portion holds the plurality of secondary batteries in series connection to a charging power source. The power supply to the secondary batteries in series connection is turned on or off by a switching circuit. A control terminal of the switching circuit is connected to a chassis exposure part of one secondary battery, the chassis exposure parts of other secondary batteries being connected to the reference voltage of the charging power source. When the primary battery is mounted, the switching circuit is turned off, because no current path from the charging power source through the plurality of secondary batteries to the reference voltage is established, whereby the batteries are not charged. Hence, it is possible to prevent the charging for the primary battery.
