Force-sense presenting apparatus

A force-sense presenting apparatus, comprising:

• a casing structure;
• a weight provided in the casing structure or incorporated in the casing structure;
• and
• a drive unit including
• a first supporting portion constituted of a first pair of supporting structures that support a first side of the weight and a second side opposed to the first side, at least one of the first pair of supporting structures being configured to include an actuator that provides the weight with biased acceleration, wherein the first supporting portion further includes a first slide structure disposed between the weight and at least one of the first pair of supporting structures, wherein the first slide structure includes a linear motion guide structure, a ball bush structure or a self-lubricating bearing structure, wherein the actuator is configured to generate first biased acceleration in a direction from the first side to the second side of the weight or a direction from the second side to the first side and wherein the first slide structure slides in a direction perpendicular to the first biased acceleration.
