Claims (1)

[Scope of utility model registration request] A material feeding member disposed at the front and rear positions of a planer barrel rotationally driven by an electric motor, and a material feeding speed switching means for changing the rotational speed from the electric motor and transmitting power to the material feeding member. , the speed switching means has first and second support shafts formed such that one shaft is driven by the electric motor and the other shaft drives the material feeding member, each having a different number of teeth. One of the large gear group and small gear group consisting of two gears is fixed to one of the two shafts, and the other gear group restrains rotation on the other shaft and slides in the axial direction. The large and small gear group is formed to be movably loosely fitted and the loosely fitted gear is displaced in the axial direction and meshed with the gear fixed to the shaft, and the gears are loosely fitted to the shaft. a shift lever having an engagement pin protruding in the radial direction so as to be able to move and drive both gears in the axial direction, the tip of which is fitted into a groove formed in the shift lever, and a locking pin protruding in the radial direction from one end side; a holding member that restrains the in the rotational direction and is loosely fitted to be slidable in the axial direction; and one end in the axial direction such that one of the gears that is loosely fitted to the shaft meshes with one of the gears that is fixed to the shaft. An elastic pressing member that biases the holding member toward the side is attached between the end face of the holding member and the stopper of the shift lever, and compresses the pressing member and slides toward the other end in the axial direction so that the locking pin presses against the holding member. The locking pin is formed to be able to guide the locking pin to a position where the other gear loosely fitted on the shaft can be engaged with the other gear fixed to the shaft while passing through the shaft and being locked on the end face. A material feeding speed switching device for an automatic plane machine, characterized by being provided with the above-mentioned shift lever.
