Lock release apparatus and lock apparatus having the same

A lock apparatus configured to lock an opening/closing member openably and closably installed on an opening section of an install-base member in a closed state,

• the lock apparatus including:
• a locking member capable of being brought into a locked state to thereby hold the opening/closing member when the opening/closing member is closed;
• a rotation member including an actuation section that rotates to actuate the locking member;
• a case member being installed on one of the install-base member and the opening/closing member and rotatably supporting the rotation member;
• an operation member slidable in a direction substantially in parallel to a rotation plane of the rotation member;
• a wound-formed spring member making contact with both the case member and the rotation member to thereby urge the rotation member in a direction in which the locking member is brought into the locked state;
• and
• a link structure converting a sliding movement of the operation member into a rotational movement of the rotation member,
• wherein the case member includes:
• an accommodation section slidably accommodating the operation member to allow an operation face thereof to be exposed;
• and
• a support section rotatably supporting the rotation member, and
• wherein, upon operation on the operation member, the operation member slides to cause the rotation member to rotate via the link structure to thereby actuate the locking member.
