Abstract
A lamp holder includes a mounting portion, a lamp holding part which is connected to the mounting portion, and includes an end capable of surrounding a peripheral surface of a lamp, and is capable of being elastically opened and deformed with attaching and detaching of the lamp. The present invention also includes a recessed portion positioned at an opposed surface to the lamp in the lamp holding part and in a position between an end portion and a connecting region to a mounting portion, such that the recessed portion allows the lamp holding part to bend so that the end portion displaces in a direction to be away from the peripheral surface of the lamp.
Claims17
A lamp holder comprising:
- a mounting portion;
- a lamp holding part connected to said mounting portion and including an end arranged to surround a peripheral surface of a lamp, and is capable of being elastically opened and deformed during attaching and detaching of the lamp to the lamp holding part;
- and
- a recessed portion positioned at an opposed surface of the lamp holding part that is opposite to said lamp and that is between an end portion and a connecting region connected to said mounting portion;
- wherein
- the recessed portion is arranged to allow the lamp holding part to bend so that said end portion displaces in a direction away from the peripheral surface of said lamp;
- said lamp holding part includes a pair of arm portions extending symmetrically in opposite directions from said mounting portion such that, when the pair of arm portions surround a lamp, the pair of arm portions surround portions of a peripheral surface of the lamp that are directly opposed in a radial direction of the lamp;
- and
- the lamp holding part includes a portion at a surface opposite to said recessed portion that bulges in a direction away from said lamp, and said lamp holding part has substantially uniform thickness over substantially an entire length thereof.
