Abstract
A holding device, includes: a holding portion configured to hold a shunt resistor; a spacer portion extending from the holding portion and abutting on a front surface of a substrate on which a monitoring unit configured to monitor a current value of a current flowing through the shunt resistor is mounted; and an engaging portion extending from the holding portion and having an engaging claw to be engaged with a back surface of the substrate. The spacer portion separates the holding portion and the substrate from each other such that a connection portion which electrically connects the shunt resistor and the monitoring unit is visible.

A holding device, comprising:
- a holding portion configured to hold a shunt resistor;
- a spacer portion extending from the holding portion and abutting on a front surface of a substrate on which a monitoring unit configured to monitor a current value of a current flowing through the shunt resistor is mounted;
- and
- an engaging portion extending from the holding portion and having an engaging claw to be engaged with a back surface of the substrate, wherein
- the spacer portion separates the holding portion and the substrate from each other such that a connection portion which electrically connects the shunt resistor and the monitoring unit is visible.
A current monitoring device, comprising:
- a shunt resistor;
- a substrate on which a monitoring unit configured to monitor a current value of a current flowing through the shunt resistor is mounted, the substrate having a front surface and a back surface;
- and
- a holding device including:
- a holding portion configured to hold the shunt resistor,
- a spacer portion extending from the holding portion and abutting on the front surface of the substrate, and
- a locking portion extending from the holding portion and including a claw portion to be locked to the back surface of the substrate, wherein
- the spacer portion separates the holding portion and the substrate from each other such that a connection portion which electrically connects the shunt resistor and the monitoring unit is visible.
A power supply device, comprising:
- a battery pack including a secondary battery cell;
- a shunt resistor electrically connected to the battery pack;
- a substrate on which a monitoring unit configured to monitor a current value of a current flowing through the shunt resistor is mounted, the substrate having a front surface and a back surface;
- a holding device including:
- a holding portion configured to hold the shunt resistor,
- a spacer portion extending from the holding portion and abutting on the front surface of the substrate, and
- a locking portion extending from the holding portion and including a claw portion to be locked to the back surface of the substrate;
- and
- a housing configured to accommodate the battery pack, the shunt resistor, the substrate, and the holding device, wherein
- the spacer portion separates the holding portion and the substrate from each other such that a connection portion which electrically connects the shunt resistor and the monitoring unit is visible.
