A friction applying apparatus and a linear guide apparatus having the
same, according to the present invention can uniformly contact allover
contacting faces of sliding members to the contacted members so as to
reduce abrasion in the sliding members and the contacted members, and may
maintain appropriate frictional force and precision. In the friction
applying apparatus forcing the sliding members moving along guide rails
for generating friction, the sliding member is made of a material having
elastic modulus being 5000 MPa or less and Vickers hardness being 400 or
more.
