A cable is sandwiched between a first inner wall surface of a peripheral-wall-side pressing wall portion and a first inner wall surface of a cap-side pressing wall portion, between a second inner wall surface of the peripheral-wall-side pressing wall portion and a second wall surface of the cap-side pressing wall portion, and between a third inner wall surface of the peripheral-wall-side pressing wall portion and a third inner wall surface of the cap-side pressing wall portion to crank the cable to form a cranked portion of the cable. The peripheral-all-side pressing wall portion and the cap-side pressing wall portion sandwich the cranked portion therebetween. Thus, defective soldering may be prevented between a plurality of lead wires and a core-wire soldered portion to which core wires of the lead wires are soldered and connected.

1. An electrical apparatus comprising: a circuit substrate unit including: a cable formed of a plurality of lead wires in a bundle; anda circuit substrate including a core-wire soldered portion provided with a plurality of electrodes to which core wires of the plurality of lead wires are soldered and connected;a casing including: an opposed wall portion facing one surface of the circuit substrate where the plurality of electrodes are provided, the opposed wall portion having a first opening portion so that the core-wire soldered portion is accessible therethrough, anda peripheral wall portion integrally formed with the opposed wall portion and surrounding an end face of the circuit substrate, the peripheral wall portion having a second opening portion formed continuously with the first opening portion, for allowing the cable to extend out therethrough; anda cap member fitted in the first and second opening portions to allow the cable to extend out through the second opening portion, whereinthe peripheral wall portion and the cap member are shaped so that the cable may be sandwiched between the peripheral wall portion and the cap member when the cap member is fitted in the first and second opening portions. 2. The electrical apparatus according to claim 1, wherein the peripheral wall portion and the cap member are shaped so that the cable may be cranked to form a cranked portion and the cranked portion of the cable may be sandwiched between the peripheral wall portion and the cap member when the cap member is fitted in the first and the second opening portions. 3. The electrical apparatus according to claim 2, wherein the peripheral wall portion and the cap member are shaped to form a first pressing structure and a second pressing structure that respectively sandwich and press either ends of the cranked portion in a longitudinal direction of the cranked portion. 4. The electrical apparatus according to claim 3, wherein the cap member includes a cap-side pressing wall portion and the peripheral wall portion includes a peripheral-wall-side pressing wall portion, the cap-side pressing wall portion and the peripheral-wall-side pressing wall portion facing each other to sandwich and press the cranked portion therebetween; andat least one of the cap-side pressing wall portion and the peripheral-wall-side pressing wall portion is integrally formed with a first pair of projecting wall portions and a second pair of projecting wall portions, the first pair of projecting wall portions being disposed adjacent to the first pressing structure and arranged side by side in a direction orthogonal to the longitudinal direction of the cable to sandwich the cable therebetween, and the second pair of projecting wall portions being disposed adjacent to the second pressing structure and arranged side by side in a direction orthogonal to the longitudinal direction to sandwich the cable therebetween. 5. The electrical apparatus according to claim 4, wherein the cap member includes: a plate-like cap body having first to fourth end faces that are continuously and annularly formed in this order, the first and third end faces being opposed to each other;a pair of shaft portions projecting respectively from end portions of the first and third end faces in the vicinity of the second end face, anda hook member integrally formed with the fourth end face at a central portion thereof;the peripheral wall portion of the casing includes a pair of shaft receiving portions disposed adjacent to the second opening portion to rotatably support the pair of shaft portions; andthe opposed wall portion of the casing includes at a rim portion surrounding the first opening portion an engaged portion for engaging with the hook member of the cap member. 6. The electrical apparatus according to claim 5, wherein the peripheral wall portion includes a peripheral wall body and an extended portion integrally formed with the peripheral wall body and extending outwardly from the peripheral wall body;the extended portion includes the peripheral-wall-side pressing wall portion and a pair of extended walls, and the extended walls extend from both end portions of the peripheral-wall-side pressing wall portion, which are adjacent to the peripheral wall body, to a position at which the extended walls are continuous with the opposed wall portion; andthe second opening portion is defined, being surrounded by the peripheral-wall-side pressing wall portion and the pair of extended walls. 7. The electrical apparatus according to claim 6, wherein the pair of extended walls are each formed integrally with a projecting portion which is located opposite to the peripheral-wall-side pressing wall portion and extending in an outward direction away from the peripheral wall body; andeach shaft receiving portion is formed by a first end face portion of the extended wall located in the outward direction and a second end face portion of the projecting portion that is continuous with the first end face portion, and the first end face portion and the second end face portion contact outer surfaces of the shaft portions to support the shaft portions. 8. The electrical apparatus according to claim 7, wherein the peripheral-wall-side pressing wall portion includes, at an end portion located in the outward direction, an extending portion extending along the pair of extended walls;the cap body includes one or more protrusions protruding from the cap body toward the peripheral-wall-side pressing wall portion when the cap member is fitted in the first and second opening portions; andside surfaces of the one or more protrusions of the cap body abut on the inner wall surface of the extending portion when an external force toward the second opening portion is applied to the cap body, and the protrusions thus work as stoppers to prevent the cap member from dropping off from the first and second opening portions. 9. The electrical apparatus according to claim 5, wherein the hook member is configured to be disengaged from the engaged portion if an external force is applied to press the cap member inwardly of the casing when the cap member is fitted in the first and second opening portions; andthe hook member is shaped and sized so that a slotted screwdriver having a tip of 8 mm or less in width may press down the hook member with the tip of the slotted screwdriver.
