Provided is a vibration suppression mechanism for an electronic device, which efficiently absorbs vibrations that adversely affect operation of the electronic device. The vibration suppression mechanism for the electronic device includes a holding unit that is constructed such that a vibration absorbing member is used at a contacting portion on a first surface of a holding member and a contact member protruding from a second surface of the holding member which is opposite to the first surface is held by the vibration absorbing member, the holding unit supporting the electronic device via the vibration absorbing member used at the contacting portion on the first surface or the contact member protruding from the second surface, and a housing for holding the holding unit in a mounted state under a state in which the contact member protruding from the second surface or the vibration absorbing member used at the contacting portion on the first surface abuts against a holding structure.
