Abstract
Provided are a car of an elevator, and an elevator that achieve weight reduction for a support frame. The support frame includes brackets at multiple locations on an upper edge, and supports a first pulley, a second pulley, and a door position detection part via the brackets. This eliminates the need to secure an area on a front face of the support frame for arranging the first pulley, the second pulley, and the door position detection part. Therefore, the height dimension of the support frame can be reduced to achieve weight reduction for the support frame.

A car of an elevator, comprising:
- a door rail, supporting a car door to be slidable in a left-right direction;
- a first pulley and a second pulley provided to be spaced apart in the left-right direction above the door rail, and a drive belt operatively connected to the car door and being wound around the first pulley and the second pulley;
- a door position detection part, detecting that the car door is at a predetermined position;
- and
- a support frame, being a plate-shaped member that is long in the left-right direction, and the support frame comprising:
- the door rail disposed on a front face of the support frame, and brackets separately disposed at a plurality of locations on an upper edge of the support frame in the left-right direction, wherein the first pulley, the second pulley, and the door position detection part are respectively supported by the brackets separately disposed,
- wherein the car door comprises a roller that engages with an upper edge of the door rail from above and rotates, and
- the upper edge of the support frame is positioned lower than an uppermost portion of the roller.
