## Abstract

An elevator motor mounting structure includes a bracket attachment part arranged above a car entrance, a bracket for supporting a motor, and a bolt for fixing the bracket to the bracket attachment part. The bracket includes a cutout that allows a shank of the bolt to enter the cutout when the bracket is attached to the bracket attachment part. The cutout has an entrance-direction cutout portion that extends inward of a car from a side end of the bracket in which the side end faces outward in an entrance direction of the car, and a width-direction cutout portion that extends from an inner end of the entrance-direction cutout portion in a width direction of the car entrance.

## Claims

### Claim 1

An elevator motor mounting structure comprising:
a bracket attachment part which a frame arranged above a car entrance includes;
a bracket that is attached to the bracket attachment part and supports a motor for opening and closing operation of a car door;
a bolt for fixing the bracket to the bracket attachment part while passing through the bracket attachment part, wherein
the bracket comprises a cutout that allows a shank of the bolt to enter the cutout when the bracket is attached to the bracket attachment part of the frame,
the cutout has, when an entrance direction of the car entrance in a plan view is a first direction and a width direction of the car entrance orthogonal to the first direction in a plan view is a second direction, an entrance-direction cutout portion that extends inward of a car from a side end of the bracket in the first direction, the side end facing outward of the car from the car entrance in the first direction, and a width-direction cutout portion that extends from an inner end of the entrance-direction cutout portion along the second direction,
the side end facing outward of the car from the car entrance in the entrance-direction cutout portion is open,
the bolt is composed of a plurality of bolts and the cutout is composed of a plurality of cutouts, respectively,
the plurality of cutouts include at least one first cutout and at least one second cutout,
the at least one first cutout has the entrance-direction cutout portion and a first width-direction cutout portion that extends from the entrance-direction cutout portion toward one side in the second direction,
the at least one second cutout has the entrance-direction cutout portion and a second width-direction cutout portion that extends from the entrance-direction cutout portion toward an other side in the second direction, and
the bracket attachment part further comprises a plurality of first penetrating parts configured to allow the bolt located at the inner end of the entrance-direction cutout portion of the at least one first cutout to move toward one end side of the first width-direction cutout portion, and allow the bolt located at the inner end of the entrance-direction cutout portion of the at least one second cutout to move toward an other end side of the second width-direction cutout portion,
further comprising:
a clamping member through which shanks of the plurality of bolts pass so as to clamp the bracket between the bracket attachment part and the clamping member,
the clamping member comprising:
a base part arranged along the bracket attachment part; and
a contact part arranged at an end on the inner side in the first direction in the base part and configured to come into contact with the motor to block the motor from moving outward in the first direction,
the base part having a plurality of second penetrating parts arranged to correspond in position to the plurality of first penetrating parts of the bracket attachment part to allow movement of the bolts.

### Claim 2 (depends on 1)

The elevator motor mounting structure according to claim 1, wherein
the base part extends in the first direction and the second direction,
the contact part extends in the second direction and a vertical direction, and
a corner formed on a boundary between the contact part and the clamping part has an arc shape with a certain radius of curvature or is a chamfered part.

### Claim 3 (depends on 1)

The elevator motor mounting structure according to claim 1, comprising:
a cover member that is attached to the bracket and covers the motor from the inner side in the first direction, wherein
the cover member has a covering part extending from a position inside the contact part to a position outside the contact part in the second direction to cover from above a cable that projects toward the one side of the motor in the second direction,
the bracket has a lateral side part extending upward from a position on the one side of the motor in the second direction and covering the motor when viewed from the second direction, and
the lateral side part has a through hole to guide the cable to the outside.
