A coupler for coupling up a rotary shaft of an ignition distributor to an engine camshaft comprises an annular member having a circular axial recess into which the rotary shaft loosely projects over one axial end of the annular member, at least one projection provided on the other axial end of the disk-like member for slidably fitting into a diametrical groove formed on a top end of the engine camshaft, a diametrical straight bore formed in the annular member, an axis of which crosses a line passing through the projection and a center of the disk-like member at an angle .theta.(0.degree.&lt;.theta.&lt;90.degree.), and a connecting pin extending through the diametrical straight bore in the annular member and a diametrical bore formed in the rotary shaft of the distributor.

A vehicle air conditioner control method and apparatus for automatically controlling the air conditioning of the compartment of a vehicle in accordance with a predetermined automatic control pattern, uses a selector for selecting a desired air conditioning condition. In response to the command signal from the selector, changeover from the control parameters, such as, air flow rate and supply air temperature for an automatic control mode to the selected control parameters for a selected air conditioning mode is effected, thus making it possible to selectively control the air conditioning of the vehicle compartment in accordance with a predetermined automatic control mode and a selected air conditioning mode.

Two vacuum chambers at the same under-atmospheric pressure produced by connection to the engine intake are provided within a common casing, and intermediate space in the casing at atmospheric pressure. The membrane of one of the vacuum chambers is connected to a flanged sleeve and the control rod which actuates the distributor timing shift is permitted to move over a limited range without coming into driving contact with either flange of the sleeve, while it is always driven by the membrane of the other vacuum chamber, to which it is affixed. Stops, including an apertured partition in the casing of one of them, and springs are provided to produce the limits and slopes of the portions of the shift characteristic that make up the composite characteristic of the device. A bellows is provided where necessary to complete the vacuum chamber system.
