Temperature sensor and rotary electric machine

A temperature sensor, comprising:

• a thermosensitive portion including a thermosensitive element and a covering body made of a resin and covering the thermosensitive element;
• an electric wire electrically connected to the thermosensitive element and drawn out from the covering body in one direction;
• and
• a holder configured to house and hold a part of the electric wire in an inside of the holder;
• wherein
• the thermosensitive portion is held by the electric wire to be displaceable at least in the one direction relative to the holder, and the part of the electric wire includes a bent region in a bent state,
• wherein a rigidity adding portion is provided around at least the bent region of the electric wire and,
• wherein the electric wire includes a first region extending from the thermosensitive portion to the bent region, and a second region extending from the bent region and drawn out to an outside of the holder,
• the rigidity adding portion includes an end on a side close to the first region and an end on a side close to the second region, the ends being positioned in the inside of the holder, and
• the end on the side close to the second region is locked to the holder from the inside, to regulate displacement of the bent region to the outside of the holder.

A temperature sensor, comprising:

• a thermosensitive portion including a thermosensitive element and a covering body made of a resin and covering the thermosensitive element;
• an electric wire electrically connected to the thermosensitive element and drawn out from the covering body in one direction;
• and
• a holder configured to house and hold a part of the electric wire in an inside of the holder, wherein
• the thermosensitive portion is held by the electric wire to be displaceable at least in the one direction relative to the holder, and
• the thermosensitive portion is displaceable in the one direction due to elastic deformation of a bent region formed in a part of the electric wire.

A rotary electric machine, comprising:

• a stator including a core and a coil;
• a rotor configured to rotate relative to the stator;
• and
• a temperature sensor, comprising:
• a thermosensitive portion including a thermosensitive element and a covering body made of a resin and covering the thermosensitive element;
• an electric wire electrically connected to the thermosensitive element and drawn out from the covering body in one direction;
• and
• a holder configured to house and hold a part of the electric wire in an inside of the holder, wherein
• the thermosensitive portion is held by the electric wire to be displaceable at least in the one direction relative to the holder due to elastic deformation of a bent region formed in a part of the electric wire, and
• the temperature sensor is configured to detect a temperature of the coil.
