Abstract
A temperature sensor detecting a temperature of a coil provided in a stator of a rotary electric machine includes: a sensor element including a thermosensitive body, electric wires electrically connected to the thermosensitive body, and an elongated covering body enclosing a part of the electric wires and the thermosensitive body, and configured to be inserted into a gap formed by the coil along a longitudinal direction of the covering body; and a bracket including a fixed portion to be fixed to the stator, and a supporting portion pressing the sensor element against the coil while elastically supporting one end of the sensor element in the longitudinal direction.

A temperature sensor detecting a temperature of a coil provided in a stator of a rotary electric machine, the temperature sensor comprising:
- a sensor element including a thermosensitive body, electric wires electrically connected to the thermosensitive body, and an elongated covering body enclosing a part of the electric wires and the thermosensitive body, and configured to be inserted into a gap formed by the coil along a longitudinal direction of the covering body;
- and
- a bracket including a fixed portion to be fixed to the stator, and a supporting portion pressing one end of the sensor element in the longitudinal direction against the coil by an elastic force of the supporting portion while supporting the covering body.
A temperature sensor comprising:
- a sensor element including a thermosensitive body, electric wires electrically connected to the thermosensitive body, and an elongated covering body enclosing a part of the electric wires and the thermosensitive body;
- and
- a bracket including a supporting portion supporting the covering body and a fixed portion to be fixed to a fixed object,
- wherein:
- the supporting portion supports the covering body in a longitudinal direction of the covering body while avoiding a region of the covering body containing the thermosensitive body;
- and
- the supporting portion is cantilevered by the fixed portion.
