Abstract: A light-emitting lure (10A) comprises a lure fish body (11), a light-emitting diode (21) arranged in the lure fish body (11) such that the light-emitting diode (21) can be observed from the outside, a substantially flat plate-like piezoelectric element (22) as a power source for allowing the light-emitting diode (21) to emit light, a power transmitting circuit (30) for transmitting the electricity generated from the piezoelectric element (22) to the light-emitting diode (21), a pair of hooks (15a, 15b) for fishing the catch, eye metallic parts (14b, 14c) for mounting the hooks (15a, 15b) to the lure fish body (11), and an eye metallic part (14a) for mounting a fishing line to the lure fish body (11).

Abstract: A slip ring with which a pair of brushes make contact includes a conducting portion which extends along an outer periphery of the slip ring over an angle of preferably about 210 degrees, and a non-conducting portion which extends over an angle of about preferably 150 degrees. A conductor which forms the conducting portion has a ring-like shape and also forms the non-conducting portion. The portion of the conductor which corresponds to the non-conducting portion has a small radius such that it is buried in an insulating resin material, a window through which an insulating resin material is exposed, or a recess through which an insulating resin material is exposed. The ring-like conductor provides a balanced center of gravity to the slip ring. The conductor may also include two or more conducting portions and two or more non-conducting portions.

Abstract: A motor case end plate structure, comprising: a motor case accommodating a motor unit therein and provided with a first radial bearing for a rotor shaft of the motor unit; a radial flange provided at an open end of the motor case; and an end plate, made of molded synthetic resin, having a second radial bearing for the rotor shaft and adapted to be attached to the motor case by way of the flange; the end plate being provided with at least three separate peripheral mounting surfaces disposed around the rotor shaft and projecting from surrounding parts so as to substantially directly abut an outer end surface of the flange of the motor case. Thereby, any error in the planeness of the mounting surfaces or any error in their perpendicularity with respect to the axial line of the motor unit can be readily corrected by shaping the part of the die for molding the end plate corresponding to the mounting surface to be corrected without requiring excessive cost or time.
