Claims

[Scope of utility model registration request]

The input shaft of the air conditioner compressor is connected to the engine crankshaft, and consists of a high-speed rotation mechanism that operates when the engine rotation speed is less than a required set value, and a low-speed rotation mechanism that operates when the engine rotation speed is higher than the set value. Control for switching the rotational force transmission device to a low-speed rotation mechanism without interfering with the engine rotation speed during an initial period of driving from the start of driving of the compressor to a required set time in a structure in which the rotational force transmission device is connected via a rotational force transmission mechanism. 1. A compressor rotation control device for a vehicle air conditioner, characterized by comprising means.
