PROBLEM TO BE SOLVED: To provide a refrigeration device that can sufficiently secure a contact area between coolant piping and a coolant jacket by a simple method.SOLUTION: A refrigeration device comprises coolant piping, a power device and a cooler. The cooler has a coolant jacket (40), a pressing plate (70) and a main lock fixing tool. The coolant jacked (40) has coolant jacket-side temporary lock pars (64 to 67). The pressing plate (70) has pressing plate-side temporary lock parts (75L, 75R). The respective temporary lock parts (64 to 67, 75L, 75R) are engaged with each other by being relatively slid in a crossing direction crossing a pressing direction in which the coolant piping is pressed against piping arrangement grooves (51L, 51R), and regulate the displacement of the pressing plate (70) in the engaged state to a direction in which the pressing plate is separated from the coolant jacket (40) by receiving a resilience force of the coolant piping. |
