Abstract
A pressure retaining member is formed by bending a metal plate. The pressure retaining member includes: a body portion supported by a housing; and two pressing portions which are connected to the body portion, can be elastically deformed, and press an optical element toward a retaining portion of the housing. One of the two pressing portions is formed with a restriction portion which restricts a depth with which the other one of the two pressing portions enters between the two pressing portions of another pressure retaining member or a depth with which the body portion of the another pressure retaining member enters between the two pressing portions.
Claims7
A pressure retaining member which presses an optical element that guides beam light to be scanned to an image-carrying member against a retaining portion of a housing to retain the optical element in the retaining portion, wherein
- the pressure retaining member is formed by bending a metal plate,
- the pressure retaining member comprises:
- a body portion supported by the housing;
- and
- two pressing portions which are connected to the body portion, can be elastically deformed, and press the optical element toward the retaining portion, and
- one of the two pressing portions is formed with a restriction portion which restricts a depth with which the other one of the two pressing portions enters between two pressing portions of another pressure retaining member.
