An elevator has a machineroom of a comparatively low height so designed that a sufficiently large working space necessary for inspection and maintenance work is available in the machineroom and a hoist cable can be wound round a traction sheave disposed in the machineroom at a large contact angle. The elevator has a cage provided with front and back cage-side sheaves and suspended for vertical movement in an elevator shaft, and a counterweight that moves vertically in a space behind a vertical plane containing the back wall of the cage in the elevator shaft. The traction sheave and a drive unit for driving the traction sheave are disposed in the machineroom with their axes laterally extended. The back cage-side sheave lies below the traction sheave.

An electric connection box including a box main body, an integration mounted at the box main body, a pair of connection devices, and a plurality of ribs. The pair of connection devices are structured with one of connection devices provided at the integration and the other of connection devices provided at the box main body. The plurality of ribs are arranged at the box main body, and abuts on the integration and is deformed when the integration is mounted at the box main body so as to prevent rattling of the integration. Second ribs among the plurality of ribs, which are arranged close to the other of connection devices, are formed stiffer than first ribs arranged away from the other of connection devices farther than the first ribs.

An electrical junction box including a box main body and a wiring block. The box main body includes a cassette block. The wiring block includes a first bus bar, a second bus bar, and a fuse. Each bus bar includes an electric parts connecting part and the power source connecting part. The electric parts connecting part is connected to electric parts attached to the cassette block. The power source connecting part includes a fuse connecting piece and a connecting piece. A terminal fitting connected to a power source is connected to the connecting piece. The fuse connects the fuse connecting pieces of the bus bars.

The present invention is intended to provide a novel assembly for properly or accurately mounting the terminal portion of the bus bar on the terminal-accommodating portion of a body for an electric junction box without doing any harm to an electrical conduit(s) which is disposed within the electric junction box. An assembly for mounting a bus bar (1) to a body (12) for an electric junction box, comprises a hole (9) disposed in the bus bar (1), and having a burr (31) created during the hole punching process; and a projection (21) formed in the body (12), and suited for being press-fit into the hole (9), wherein the projection (21) extends beyond the burr after being press-fit into the hole (9). In this configuration, the hole (9) may serve as a basis for position determination of each terminal portion (3, 4) of the bus bar (1), and the projection (21) may serve as a basis for position determination of each terminal-accommodating portion (25) of the body (12). A pair of the holes (9) may be spaced apart from each other in a longitudinal direction of the bus bar (1), and a pair of the projections (21) may be correspondingly formed in the body (12) so as to be press-fit into the holes (9). The projection (21) may have a plurality of press-fit ribs (29) extending outwardly from a peripheral surface thereof, and being approximately triangular in traverse cross-section.

A block body made of insulating synthetic resin having a terminal supporting plate in one piece therewith. A plurality of elongated ribs project on one surface of the terminal supporting plate and a rescue terminal is arranged on the other surface of the terminal supporting plate. A bus bar is mounted in the block body. A clamping portion of a booster cable can grasp both the rescue terminal and the rib at one time. The plurality of ribs are parallel to each other. The dimension of the rib is defined such that the rib is placed under compressive deformation when the rib is clamped by the clamping portion. The block body has a hole through which the rescue terminal is passed such that the rescue terminal extends along and in contact with the other surface of the terminal supporting plate.
