A manipulation device has a manipulation body rotationally operated by the manipulator, a support body rotatably supporting the manipulation body, and a rotational load imparting mechanism. The rotational load imparting mechanism has a movable member engaged with the rotational axis of the manipulation body, a magnetism generating mechanism facing the movable member with a gap intervening, and a magnetic viscous fluid, its viscosity changing according to the strength of a magnetic field. The magnetism generating mechanism has a coil generating a magnetic field and a first yoke provided so as to enclose the coil. The first yoke has a first opposing part and second opposing part, which are separated by slits, on a side facing the movable member. The magnetic viscous fluid is filled in the gap, which is between the first opposing part and the movable member and between the second opposing part and the movable member.

In a shift device, a shift locking mechanism drives a motor to perform locking and locking release of rotation of a knob, and an autocorrect mechanism drives the motor to change a shift position of the knob to a P position. Thus, driving of the common motor enables locking and locking release of the rotation of the knob to be performed, and enables a shift position of the knob to be changed to the P position, thereby enabling a simple configuration.

A park lock system for a shifter of an automatic transmission, according to one embodiment, includes a blocking member pivotal between a locked position to prevent movement of the shifter and an unlocked position for allowing movement of the shifter. At least a portion of the blocking member may include hard magnetic properties, such as having a permanent magnet coupled therewith. An electromagnet may have a core member proximate the magnetic portion of the blocking member to cause the blocking member to move to or remain in the locked position when the electromagnet is de-energized. Accordingly, when the electromagnet is energized, the electromagnet may be configured to generate a magnetic field in repelling polarity to the magnetic portion that causes the blocking member to move to the unlocked position.

The invention relates to an activation device (1) for a parking brake with a parking brake lever (2) swivel-mounted on a bearing block (3) and with a blocking device comprised of a pawl (13) on the parking brake lever (2) and a locking segment (12) on the bearing block (3). The parking brake lever (2) is fixed in place in a swivel position via the engagement of the pawl (13) with the locking segment (12). The swivel position of the parking brake lever (2) is transmitted via a transmission element to the parking brake and with a transfer device in or on the parking brake lever (2). The engagement of the pawl (13) with the locking segment (12) is released by actuating the transfer device. To form a swivel bearing, a shaft is provided to which a holder (7) for the transmission element and the parking brake lever (2) can be affixed in different rotational positions. As an alternative, or in addition, a linear movement of the pawl (13) is brought about by means of the transfer device.
