Optical component housing, and projector using the same

A projector having an optical component housing formed by thixomolding using a metal material, said optical component housing having an optical component positioning portion, said optical component positioning portion comprising:

• a first side plate and a second side plate that form a predetermined angle;
• a first support portion that supports one of a light incident surface and a light emitting surface of said optical component;
• and
• a second support portion that supports a peripheral edge portion of said optical component, said first support portion projecting on an inner side face of said first side plate so as to be in contact with said second side plate, and a portion of said second side plate in contact with said first support portion having a portion previously removed that is formed by inserting an insert in a mold used in the thixomolding.

An optical component housing formed by thixomolding using a metal material, and having an optical component positioning portion, said optical component positioning portion comprising:

• a first side plate and a second side plate that form a predetermined angle;
• a first support portion that supports one of a light incident surface and the light emitting surface of said optical component;
• and
• a second support portion that supports a peripheral edge portion of said optical component, said first support portion projecting on an inner side face of said first side plate so as to be in contact with said second side plate, and a portion of said second side plate in contact with said first support portion having a recess.
