The output lever rotates so as to operate a first link portion on a side toward a first direction with respect to a rotational center of the output lever.

A switch includes: a tank; a fixed contact and a reciprocally movable contact provided inside the tank; an opening/closing shaft that rotates to thereby move the movable contact; a jack base fixed to the outer side of the tank; a torsion bar that stores a force to rotate the opening/closing shaft so as to move the movable contact in a direction away from the fixed contact; and an opening/closing lever detachably attached to the opening/closing shaft. The jack base has a first penetrating portion formed therethrough and facing the opening/closing lever. The opening/closing lever has a second penetrating portion formed therethrough and facing the jack base. The switch further includes: a bolt inserted through the first penetrating portion and the second penetrating portion; and a nut attached to a portion of the bolt, the portion of the bolt extending out of the first penetrating portion and the second penetrating portion.

Switch

A switchgear includes a movable part capable of reciprocating movement, a movable contact coupled to the movable part, a member that biases the movable contact, a latch capable of switching between a first state in which movement of the movable contact is restricted and a second state in which movement is permitted, a part that accommodates the movable part and the movable contact therein, a fixed contact provided outside of the accommodating part, and a moving part that moves with the movable contact. The latch is switched to the second state when the movable contact has moved against the biasing force. The accommodating part contains a first region and a second region, which is on a side of the fixed contact with respect to the first region within a range of movement of the moving part. The first region has an inner diameter smaller than that of the second region.

Switchgear

A vehicle seatincludes a seat cushionfor supporting the buttocks of an occupant, a backresthaving a seat backand supporting the back of the occupant, and a reclining mechanismhaving a bracketthat rotates about a rotation axis C and enabling the backrestto rotate relative to the seat cushion. The bracketis fastened onto a side surface plateof the seat backby a first bolt, a second bolt, and a third boltthat pass through the bracketand the side surface plate. An insertion position for the third boltis offset from a straight line L passing through an insertion position for the first boltand an insertion position for the second bolt

Vehicle seat

An operating device includes: a lever rotatable about a rotating axis; a first torsion bar extending in a first direction along the rotating axis; a second torsion bar provided inside the first torsion bar, extending along the rotating axis, coupled to the first torsion bar at a portion located farther in the first direction than the lever, and extending from the portion of coupling with the first torsion bar toward a second direction opposite to the first direction beyond the lever; and a third torsion bar surrounding the second torsion bar, having a tubular shape, coupled to the second torsion bar at a portion located farther in the second direction than the lever, and extending from the portion of coupling with the second torsion bar in the first direction.

Operating device and circuit breaker

An operating device includes a lever rotatable about a rotating axis, a first torsion bar connected to the lever, and a second torsion bar connected to one end of the first torsion bar. The operating device further includes: a support fixedly supporting the second torsion bar at an end opposite to an end connected to the first torsion bar; a first pedestal portion structured to sandwich the support with a central axis of the second torsion bar interposed, the first pedestal portion supporting the support such that the support is rotatable about the central axis; a second pedestal portion including a penetrating portion extending through the second pedestal portion toward the support; a bolt including a shank passing through the penetrating portion, the bolt being screwed into the first pedestal portion; and a nut attached to the shank between the second pedestal portion and a head of the bolt.

A gas insulated bus is provided which comprises a metallic container whose axis is an axis line; a main circuit conductor housed in the metallic container; a metallic container to be connected with an end of the metallic container and whose axis is an axis line crossing the axis line; a main circuit conductor housed in the metallic container; an insulating spacer of a single-leg structure that supports and insulates a connection portion of the main circuit conductors; a metal-made shield attached to the insulating spacer and provided with an opening open in a direction of the axis line and an opening open in a direction of the axis line, the shield covering the connection portion, the shield being substantially in a barrel or spindle shape having an outside diameter exceeding that of the main circuit conductors.

A circuit closer includes: a vacuum interrupter in which one of a pair of electrodes oppositely disposed in a vacuum vessel, wherein a gap d between the pair of electrodes always satisfies d&#x3e;0, and a gap dbetween the pair of electrodes in a state in which closing of a circuit is completed, is shorter than a distance dat which insulation between the pair of electrodes is broken down by a charge voltage V of the circuit that is to be closed, and is longer than a distance dat which the pair of electrodes are bridged by a deposition of an electrode metal after a closing operation, the deposition resulting from evaporation caused by heat of an arc generated when the circuit is closed.
