A spacer for a foreign object detection sensor including an elongated hollow sheath, two conductive members, and two core wires buried in the two conductive members, the spacer being used for a terminal portion of the foreign object detection sensor and including a first member including an insertion portion configured to be inserted into a space between the two conductive members, and a concave-shaped second member including a first end portion and a second end portion, the first end portion at which a locking portion is provided to be locked to a first end of the first member, the second end portion which is opposed to the locking portion and is connected to a second end of the first member via an integral hinge, the second member containing one of the two conductor portions inside a closed cross-section formed between the first member and the second member.

A rotary mold type injection molding machine and a method for exchanging mold members of a rotary mold type injection molding machine are provided which enable relatively easy mold member exchange in a short time. The rotary mold type injection molding machine includes a fixed platen, a movable platen which is opened and closed in a horizontal direction with respect to the fixed platen, and a rotary table to which mold members are mounted and which is rotatably provided on one of the fixed platen and the movable platen. A mold-member moving mechanism which horizontally moves the mold member upon mold member exchange is provided on the rotary table.
